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 a trapezoid?

Back

Trapezoids have one pair of parallel sides, the non-parallel sides are called legs, and the angles adjacent to each leg are supplementary.

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 midsegment of a trapezoid?

Back

The midsegment of a trapezoid is the line segment that connects the midpoints of the two non-parallel sides and is parallel to the bases.

Front

How do you calculate the length of the midsegment in a trapezoid?

Back

The length of the midsegment (XY) can be calculated using the formula: XY = (Base1 + Base2) / 2.

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 (A) of a trapezoid can be calculated using the formula: A = (Base1 + Base2) / 2 * height.

Front

What are the legs of an isosceles trapezoid?

Back

The legs of an isosceles trapezoid are the two non-parallel sides that are congruent.

Front

If the bases of a trapezoid are 10 and 14, what is the length of the midsegment?

Back

The length of the midsegment is (10 + 14) / 2 = 12.

Front

What is the relationship between the angles of a trapezoid?

Back

In a trapezoid, the angles adjacent to each leg are supplementary, meaning they add up to 180 degrees.
