Chapter 4 Pretest

Front

What are polygons?

Back

Polygons are two-dimensional shapes made up of straight line segments that are connected to form a closed figure.

Front

Name two types of polygons.

Back

Examples include triangles, squares, rectangles, trapezoids, and parallelograms.

Front

What is the formula for the area of a parallelogram?

Back

Area = base × height.

Front

If the area of a parallelogram is 130 square yards and the base is 13 yards, what is the height?

Back

Height = Area / base = 130 / 13 = 10 yards.

Front

What is the perimeter of a shape?

Back

The perimeter is the total distance around the outside of a shape.

Front

How do you calculate the perimeter of a rectangle?

Back

Perimeter = 2 × (length + width).

Front

What is the area of a rectangle?

Back

Area = length × width.

Front

If a composite figure is made up of a rectangle and a triangle, how do you find its area?

Back

Calculate the area of each shape separately and then add them together.

Front

What is a trapezoid?

Back

A trapezoid is a four-sided figure (quadrilateral) with at least one pair of parallel sides.

Front

What is the area of a trapezoid?

Back

Area = (1/2) × (base1 + base2) × height.
