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 properties of consecutive interior angles in a trapezoid?

Back

Consecutive interior angles in a trapezoid are supplementary, meaning they add up to 180 degrees.

Front

What is true about alternate interior angles in a trapezoid?

Back

Alternate interior angles are congruent when a transversal crosses two parallel lines.

Front

What is an isosceles trapezoid?

Back

An isosceles trapezoid is a trapezoid where the non-parallel sides (legs) are equal in length.

Front

What can be said about the base angles of an isosceles trapezoid?

Back

The base angles of an isosceles trapezoid are congruent.

Front

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

Back

The legs of an isosceles trapezoid are congruent.

Front

How do you identify the parallel sides in a trapezoid?

Back

The parallel sides in a trapezoid are called the bases.

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

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 the diagonals in a trapezoid?

Back

In a trapezoid, the diagonals may or may not be congruent, depending on whether it is isosceles or not.
