Properties of Trapezoids

Front

What is a trapezoid?

Back

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

Front

How many pairs of parallel sides does a trapezoid have?

Back

A trapezoid has exactly 1 pair of parallel sides.

Front

What are the bases of a trapezoid?

Back

The parallel sides of a trapezoid are called the bases.

Front

What is an isosceles trapezoid?

Back

An isosceles trapezoid is a trapezoid in which the non-parallel sides (legs) are congruent.

Front

What is the sum of the interior angles of a trapezoid?

Back

The sum of the interior angles of a trapezoid is 360 degrees.

Front

True or False: A trapezoid has two bases.

Back

True.

Front

What is a property of isosceles trapezoids regarding angles?

Back

In an isosceles trapezoid, each pair of base angles is congruent.

Front

What is the relationship between consecutive angles in a trapezoid?

Back

In a trapezoid, each pair of consecutive angles is supplementary (adds up to 180 degrees).

Front

What is the formula for finding the area of a trapezoid?

Back

Area = (1/2) * (Base1 + Base2) * Height.

Front

If the lengths of the bases of a trapezoid are 10 and 6, and the height is 4, what is the area?

Back

Area = (1/2) * (10 + 6) * 4 = 32 square units.
