Front

A trapezoid is a quadrilateral with exactly one pair of _____ sides.

Back

Front

The legs of an isosceles trapezoid are _____.

Back

congruent

Front

Interior angles of a trapezoid add up to _____.

Back

360 degrees

Front

The diagonals of an isosceles trapezoid are congruent. True or False?

Back

True

Front

What is the sum of the interior angles of any quadrilateral?

Back

360 degrees

Front

In a trapezoid, the bases are the two parallel sides. True or False?

Back

True

Front

If one angle of a trapezoid is 79°, what is the measure of the adjacent angle if the trapezoid is isosceles?

Back

79° (the adjacent angle is equal in an isosceles trapezoid).

Front

What is the relationship between the angles on the same side of a trapezoid?

Back

They are supplementary (add up to 180°).

Front

In a trapezoid, if one base is longer than the other, what can be said about the angles adjacent to the longer base?

Back

They are smaller than the angles adjacent to the shorter base.

Front

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

Back

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