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

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 property of the angles in a trapezoid?

Back

In a trapezoid, each pair of consecutive angles is supplementary, meaning they add up to 180 degrees.

Front

What are the legs of a trapezoid?

Back

The non-parallel sides of a trapezoid are called the legs.

Front

How do you find the length of the bases in a trapezoid?

Back

The length of the bases can be found using the properties of trapezoids and the lengths of the legs.

Front

What is the relationship between the diagonals of an isosceles trapezoid?

Back

In an isosceles trapezoid, the diagonals are congruent.

Front

True or False: A trapezoid has two bases.

Back

True.

Front

What is the formula for the area of a trapezoid?

Back

The area of a trapezoid can be calculated using the formula: Area = (1/2) * (Base1 + Base2) * Height.

Front

What is the significance of congruent legs in an isosceles trapezoid?

Back

The congruent legs of an isosceles trapezoid ensure that the angles adjacent to each base are equal.
