Geometry ACT Final Exam Review

Front

What is the formula for the area of a rectangle?

Back

The area of a rectangle is calculated using the formula: Area = length × width.

Front

What is the formula for the perimeter of a rectangle?

Back

The perimeter of a rectangle is calculated using the formula: Perimeter = 2(length + width).

Front

If a rectangle has an area of 120 square inches and a perimeter of 68 inches, how can you find its dimensions?

Back

You can set up a system of equations using the area and perimeter formulas to solve for length and width.

Front

What does it mean for two rectangles to be similar?

Back

Two rectangles are similar if their corresponding sides are in proportion and their angles are equal.

Front

How do you calculate the area of similar rectangles?

Back

The area of similar rectangles can be calculated using the ratio of their corresponding side lengths squared.

Front

If the area of rectangle ABCD is 60 square inches, how do you find the perimeter of similar rectangle EFGH?

Back

Use the ratio of the areas to find the ratio of the sides, then calculate the perimeter using the side lengths.

Front

What is the relationship between the angles in a quadrilateral?

Back

The sum of the interior angles in a quadrilateral is always 360 degrees.

Front

How do you find the measure of an unknown angle in a quadrilateral?

Back

You can find the measure of an unknown angle by subtracting the sum of the known angles from 360 degrees.

Front

What is the significance of the dimensions of a rectangle in real-world applications?

Back

The dimensions of a rectangle can represent physical objects, helping to calculate space, area, and material requirements.

Front

How do you determine the dimensions of a rectangle given its area and perimeter?

Back

Set up equations based on the area and perimeter formulas, then solve the system of equations.
