What Is a Geometric Pattern in Math? : Math Definitions & More

The shape formed is approximately a parabola. See link for some more details about the construction.

Generally, constructions like this seem to be called “geometric string art”.

  • $\begingroup$One can make a parabola by using lines in this manner, but that doesn’t make this a parabola.$\endgroup$ SemiclassicalJul 22, 2014 at 6:06
  • $\begingroup$@Semiclassical I’m not sure what you’re getting at. Is it that this is only an approximation to a parabola?$\endgroup$ user165670Jul 22, 2014 at 6:08
  • $\begingroup$You’re right. But I just want to know the general name for patterns like this .$\endgroup$Jul 22, 2014 at 6:08
  • 2$\begingroup$The general pattern is an envelope. But I’m trying to confirm something, and I may’ve jumped too quick on you .$\endgroup$Jul 22, 2014 at 6:09

Summing A Geometric Series

We can use this handy formula:

a is the first term r is the “common ratio” between terms n is the number of terms

What is that funny symbol? It is called Sigma Notation

means “sum up”

And below and above it are shown the starting and ending values:

It says “Sum up n where n goes from 1 to 4. Answer=10

The formula is easy to use … just “plug in” the values of a, r and n

Example: Grains Of Rice On A Chess Board

On the page Binary Digits we give an example of grains of rice on a chess board. The question is asked:

When we place rice on a chess board:

  • 1 grain on the first square,
  • 2 grains on the second square,
  • 4 grains on the third and so on,

doubling the grains of rice on each square …

… how many grains of rice in total?

So we have:

= 12641 = 264 1

= 18,446,744,073,709,551,615

Which was exactly the result we got on the Binary Digits page

And another example, this time with r less than 1:

Geometric patterns can be a great, creative way to spice up ordinary photos. For example, Sorry Colour takes a variety of photos and pastes them into shapes. The collage ultimately offers an entirely different, unique experience, giving the images more personality than if they were displayed alone.

Multiplying Or Dividing With The Same Number

Take another look at sequence F: 2 6 18 54 162 486 …

Piet explains that he figured out how to continue the sequence F:

I looked at the first two terms in the sequence and wrote \.

When I multiplied the first number by 3, I got the second number: \.

I then checked to see if I could find the next number if I multiplied 6 by 3: \.

I continued checking in this way: \ and so on.

This gave me a rule I can use to extend the sequenceand my rule was:multiply each number by 3 to calculate the next number in the sequence.

Zinhle says you can also find the pattern by working backwards and dividing by 3 each time:

The number that we multiply with to get the next term in the sequence is called a ratio. If the number we multiply with remains the same throughout the sequence, we say it is a constant ratio.

  • Check whether Piet’s reasoning works for sequence H: 2 4 8 16 32 64 …
  • Describe, in words, the rule for finding the next number in the sequence. Also write down the next five terms of the sequence if the pattern is continued.

  • Examples Of Arithmetic And Geometric Pattern

    Example 1:

    Determine the value of P and Q in the following pattern.

    85, 79, 73, 67, 61, 55, 49, 43, P, 31, 25, Q.

    Solution:

    Given sequence:85, 79, 73, 67, 61, 55, 49, 43, P, 31, 25, Q.

    Here, the number is decreasing by 6

    The previous number of P is 43. So, P will be 43 6, P = 37

    The previous number of Q is 25. So, Q will be 25 6, Q = 19

    Therefore, the value of P is 37 and Q is 19.

    Example 2:

    Determine the value of A and B in the following pattern.

    15, 22, 29, 36, 43, A, 57, 64, 71, 78, 85, B.

    Solution:

    Given sequence: 15, 22, 29, 36, 43, A, 57, 64, 71, 78, 85, B.

    Here, the number is increasing by +7

    The previous number of A is 43. So, A will be 43 + 7, A = 50

    The previous number of B is 85. So, B will be 85 + 7, B = 92

    Therefore, the value of A is 50 and B is 92.

    Example 3:

    Find the missing value in the geometric pattern: 120, 60, __, 15, __.

    Solution:

    Given: Geometric pattern is 120, 60, __, 15, __.

    In this geometric pattern, the rule used is Divide the previous term by 2 to get the next term.

    120/2 = 60

    Then, the first missing term = 60/2 = 30

    Second Missing term = 15/2 = 7.5

    Hence, the geometric sequence is 120, 60, 30, 15, 7.5.

    Choose Uncommonly Used Shapes

    No one says you have to stick to the standard circles, squares, and triangles in fact, a design might work better using less traditional shapes.

    Fenix Music, for example, uses speech bubbles and lightning bolts to highlight certain elements, a design which works better due to the connection to the subject matter.

    Rules For Patterns In Maths

    Geometric Patterns

    To construct a pattern, we have to know about some rules. To know about the rule for any pattern, we have to understand the nature of the sequence and the difference between the two successive terms.

    Finding Missing Term: Consider a pattern 1, 4, 9, 16, 25, ?. In this pattern, it is clear that every number is the square of their position number. The missing term takes place at n = 6. So, if the missing is xn, then xn = n2. Here, n = 6, then xn = 2 = 36.

    Difference Rule: Sometimes, it is easy to find the difference between two successive terms. For example, consider 1, 5, 9, 13,. In this type of pattern, first, we have to find the difference between two pairs of the sequence. After that, find the remaining elements of the pattern. In the given problem, the difference between the terms is 4, i.e.if we add 4 and 1, we get 5, and if we add 4 and 5, we get 9 and so on.

    How Do You Create Geometric Patterns

    There is an infinite variety of geometric patterns you can create. You can create a simple pattern or complicated patterns, and you can create them yourself using graphic design software, or you can use generative programs to create a digital pattern. You might choose to use basic shapes on their own for your design or combine a variety of shapes to build a geometric image.

    There are plenty of generative software tools that produce geometric patterns automatically, like Normform and Blocco.

    Examples Of Geometric Patterns In Graphic Design

    Geometry is everywhere – in our architecture, household items, clothes, websites, and apps. It is one of the fundamental scientific building blocks that lets us study and interpret our universe, so it only makes sense that we’d see it in our art, technology, and everyday items.

    Because shapes are such a fundamental part of life, they have the power to communicate particular messages and create beautiful designs in the form of geometric patterns.

    In this article, we’ll look at the many ways in which geometric patterns can be used in graphic design, as well as the different types of geometric patterns we can create. Let’s get started!

    Visual Number Talk Prompt

    Student prompt:

    Use manipulatives or draw what you think might come next.

    At this point, it is important for students to understand that there is really no way to guarantee what will come next because we do not have enough information yet. Here are some of the predictions students might make and some possible reasoning:

    • 9 acorns because the pattern is growing by 3 acorns per day
    • 12 acorns because the pattern is doubling each day.
    • 3 acorns because the pattern is repeating and,
    • Other possibilities.

    Next, show students the number of acorns in total on day 3 and ask them to make another prediction for how many acorns there will be on day 4.

    You may notice that more and more students update their predictions to a pattern increasing by 3 acorns per day .

    Once we share how many acorns were collected over the first four days, we can ask students:

    Assuming this pattern continues, describe the pattern rule in words to your neighbour.

    As students continue discussing how they might describe the pattern rule, you can extend this prompt to:

    Describe what day 14 and what day 21 will look like.

    Articulate to students that the purpose of a pattern rule is to help someone easily understand how a pattern changes from day to day . In the case of a geometric pattern , it is also helpful to describe how the visual pattern is growing without necessarily being able to see the pattern with their own eyes.

    Definition And Representation Of Geometric Patterns

    The teacher will ask students to work in pairs to cope with the task of using different patterns. Since students are just beginning to get acquainted with geometric patterns, the question will be open-ended: do you see the pattern? After that, choose any method and try using it to represent the pattern. Students, divided into pairs, will tell the class their opinion orally. During the discussion, the teacher will provide the class with another pattern for analysis, but this time it will be completely different. Students will work with this pattern, again choosing any method, and the result of their work should be ways of expressing a geometric pattern. Then, students will be offered a discussion concerning the method of representing a numerical pattern using diagrams. The teacher can evaluate students during discussions and work with representations of geometric patterns. For consolidation, students will be offered a similar to the previous task.

    Mention Two Different Types Of Number Patterns

    Geometric Number Patterns

    The two different types of number patterns are:

    • Arithmetic Pattern – This is a sequence of numbers which are related to each other and are usually based on addition or subtraction.
    • Geometric Pattern – This is a sequence of numbers that are related to each other and are based on the multiplication and division operation.

    How To Teach Patterns In Math

    Patterns can be taught through simple exercises like arranging different beads in a string in a particular order, or taking the building blocks of different shapes and sizes and arranging them in a particular sequence which creates a series. For number patterns, the factors, multiples, squares, and cubes of numbers help in understanding patterns easily

    Girih Tilings And Woodwork

    Girih are elaborate interlacing patterns formed of five standardized shapes. The style is used in Persian Islamic architecture and also in decorative woodwork. Girih designs are traditionally made in different media including cut brickwork, stucco, and mosaic faience tilework. In woodwork, especially in the Safavid period, it could be applied either as lattice frames, left plain or inset with panels such as of coloured glass or as mosaic panels used to decorate walls and ceilings, whether sacred or secular. In architecture, girih forms decorative interlaced strapwork surfaces from the 15th century to the 20th century. Most designs are based on a partially hidden geometric grid which provides a regular array of points this is made into a pattern using 2-, 3-, 4-, and 6-fold rotational symmetries which can fill the plane. The visible pattern superimposed on the grid is also geometric, with 6-, 8-, 10- and 12-pointed stars and a variety of convex polygons, joined by straps which typically seem to weave over and under each other. The visible pattern does not coincide with the underlying construction lines of the tiling. The visible patterns and the underlying tiling represent a bridge linking the invisible to the visible, analogous to the “epistemological quest” in Islamic culture, the search for the nature of knowledge.

    Type Of Candlestick Patterns

    Candlestick patterns are created by grouping two or more candlesticks in a certain manner. They are used by technical analysts to identify trading patterns and set up trades. Candlestick charts have their origin in Japan. This was there 100 years before the bar charts and point-and-figure charts were there in use. The white rectangular part of the candle is called the real body. It shows the link between the opening and closing prices. Candlestick patterns can be classified into:

    • Continuation Patterns
    • Bearish Reversal Patterns

    Why Does The Formula Work

    #regolo54 #Fractal #Fibonacci #geometry #symmetry #pattern #math # ...

    Let’s see why the formula works, because we get to use an interesting “trick” which is worth knowing.

    First“S”NextSr

    Notice that S and S·r are similar?

    Now subtract them!

    Wow! All the terms in the middle neatly cancel out.

    S S·r = a arn

    Let’s rearrange it to find S:

    Saa

    Which is our formula :

    So what happens when n goes to infinity?

    We can use this formula:

    But be careful:

    r must be between 1 and 1

    and r should not be 0 because the sequence is not geometric

    So our infnite geometric series has a finite sum when the ratio is less than 1

    Let’s bring back our previous example, and see what happens:
