Geometry Word Problems Involving Similar Triangles

Math Practice Problems – Basic Algebra and One-Step Equations

Indirect Measurement Using Similar Triangles

This video illustrates how to use the properties of similar triangles to determine the height of a tree.

How to solve problems involving Similar Triangles and Proportions?

Examples:

  • Given that triangle ABC is similar to triangle DEF, solve for x and y.

  • The extendable ramp shown below is used to move crates of fruit to loading docks of different heights.When the horizontal distance AB is 4 feet, the height of the loading dock, BC, is 2 feet. What is the height of the loading dock, DE?

  • Triangles ABC and ABC’ are similar figures. Find the length AB.

  • How to use similar triangles to solve a geometry word problem?

    Examples:Raul is 6 ft tall and he notices that he casts a shadow thats 5 ft long. He then measures that the shadow cast by his school building is 30 ft long. How tall is the building?

    Geometry Word Problems Involving Perimeter

    Example:A triangle has a perimeter of 50. If 2 of its sides are equal and the third side is 5 morethan the equal sides, what is the length of the third side?

    Solution:

    Let x = length of the equal sides Sketch the figure

    Step 2: Write out the formula for perimeter of triangle.

    P = sum of the three sides

    Step 3: Plug in the values from the question and from the sketch.

    50 = x + x + x+ 5

    Be careful! The question requires the length of the third side.

    The length of third side = 15 + 5 = 20

    Answer: The length of third side is 20.

    Geometry Word Problems Involving Angles

    Example 1:In a quadrilateral two angles are equal. The third angle is equal to the sum of the two equal angles. The fourth angle is 60° less than twice the sum of the other three angles. Find the measures of the angles in the quadrilateral.

    • The question requires the values of all the angles.Substituting x for 35, you will get: 35, 35, 70, 220

      Answer: The values of the angles are 35°, 35°, 70° and 220°.

    Example 2:The sum of the supplement and the complement of an angle is 130 degrees. Find the measure of the angle.

    Overview Of The Sat Math Test

    The SAT Math Test consists of two sections: No calculator and Calculator. The No calculator section asks you to answer 20 questions in 25 minutes and the Calculator section asks you to answer 38 questions in 55 minutes. Your scores in both these sections are combined and scaled to be out of 800, or half of your total SAT score.

    There are four categories of questions on the SAT Math Test:

  • Additional Topics in Math
  • Geometry questions fall under the fourth category, and constitute around 10% of the SAT math test, or around 57 questions. The SAT expects you to know basic geometric concepts, like the properties of angles, shapes, and solids. But, you are given a few formulas to help you out with these problems:

    However, we recommend having these formulas memorized. This will not only save you the time of flipping back and forth through your test booklet, but will also give you an idea of where to start when encountered with an unfamiliar problem.

    Geometry Word Problems Involving Area

    Example 1:A rectangle is 4 times as long as it is wide. If the length is increased by 4 inches and the width is decreased by 1 inch, the area will be 60 square inches. What were the dimensions of the original rectangle?

    • We get two values for x.

      Since x is a dimension, it would be positive. So, we take x = 4

      The question requires the dimensions of the original rectangle.The width of the original rectangle is 4.The length is 4 times the width = 4 × 4 = 16

      Answer: The dimensions of the original rectangle are 4 and 16.

    Example 2:This is a geometry word problem that we can solve by writing an equation and factoring.The height of a triangle is 4 inches morethan twice the length of the base. The area of the triangle is 35square inches. Find the height of the triangle.

    Algebra Question Types And Tips

    We hope these algebra practice problems and answers have helped you.

    The algebra questions on your examination will usually include three main types of problems.

    Substituting Values

    Performing operations with algebraic expressions and formulas, like in this example.

    What is the value of the following expression when x = 2 and y = 2 ?

    In these algebra practice problems, you need to substitute for x and y and answer.

    Rational Numbers & Radicals

    There will also be computations on equations with integers, rational numbers, and radicals.

    Integers are whole numbers. In other words, they are not fractions or decimals.

    You may have to simplify an equation that contains only integers.

    Tips:

    Two negative signs together make a positive.

    Complete the operations inside the parentheses first.

    Remember to be careful when multiplying the negative numbers.

    Solutions To The Algebra Problems

    Solutions and explanations for each of the answers to the algebra practice problems are provided in this section.

    Solution 1:

    Polynomials are algebraic expressions that contain more than one term.

    You will definitely have questions on your algebra exam about multiplying polynomials.

    When multiplying polynomials, you should use the F-O-I-L method.

    This means that you multiply the variables two at a time from each of the two parts of the equation in the parentheses in this order:

    First Outside Inside Last

    So, the first variables in each set of parentheses are 2x and 2x

    FIRST:

    The variables on the outside of each set of parentheses are 2x and 3y

    OUTSIDE:

    The variables on the inside of each set of parentheses are -3y and 2x

    INSIDE:

    The last variables in each set of parentheses are -3y and -3y

    LAST:

    Then we add all of the above parts together to get:

    Solution 2:

    Algebra practice problems usually include inequalities problems and answers. Inequalities contain the less than or greater than signs.

    In order to solve inequalities, deal with the whole numbers on each side of the equation first:

    31 2/3x> 27

    2/3x>

    2/3x > -4

    Then deal with the fraction:

    2/3x> -4

    Geometry Math Problem Involving The Perimeter Of A Rectangle

    The following two videos give the perimeter of a rectangle, a relationship between the length and width of the rectangle, and use that information to find the exact value of the length and width.

    Example:A rectangular landing strip for an airplane has perimeter 8000 ft. If the length is 10 ft longer than 35 times the width, what is the length and width?

    Examples of perimeter geometry word problemsThis video shows how to write an equation and find the dimensions of a rectangle knowing the perimeterand some information about the about the length and width.

    Example:The width of a rectangle is 3 ft less than its length. The perimeter of the rectangle is 110 ft.Find the dimensions.

    Perimeter Word Problems
