Trapezoids

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 an isosceles trapezoid?

Back

An isosceles trapezoid has one pair of parallel sides, and 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°.

Front

What are base angles in a trapezoid?

Back

Base angles are the angles that are adjacent to each base (the parallel sides) of the trapezoid.

Front

In an isosceles trapezoid, how do the base angles relate to each other?

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

If one angle of a trapezoid is 70°, what is the measure of the opposite angle?

Back

The opposite angle is also 70° if the trapezoid is isosceles; otherwise, it can vary.

Front

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

Back

The length of the bases can be found using the formula: Area = (1/2) * (Base1 + Base2) * Height.

What is a median of a trapezoid?

Back

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