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 is the definition of an isosceles trapezoid?

Back

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

Front

What are the properties of the angles in a trapezoid?

Back

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

Front

Are the base angles of an isosceles trapezoid congruent?

Back

Yes, the base angles of an isosceles trapezoid are congruent.

Front

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

Back

The diagonals of an isosceles trapezoid are congruent.

Front

What is the measure of the angles in a trapezoid?

Back

The angles in a trapezoid can vary, but the sum of the angles is always 360 degrees.

Front

What is the difference between a trapezoid and a parallelogram?

Back

A trapezoid has at least one pair of parallel sides, while a parallelogram has two pairs of parallel sides.

Front

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

Back

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

Front

What can be said about the legs of an isosceles trapezoid?

Back

The legs of an isosceles trapezoid are congruent.

Front

What is the measure of the angles adjacent to the bases of a trapezoid?

Back

The angles adjacent to each base are supplementary.
