Geometry Word Problems Involving Similar Triangles
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:
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.

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
