Trapezoids

Front

What is a trapezoid?

Back

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

Front

What are the legs of an isosceles trapezoid?

Back

The legs of an isosceles trapezoid are congruent.

Front

If AD = 3x + 4 and BC = 8x - 11, find the value of AD when BC = 13.

Back

AD = 13.

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

In a trapezoid, if one angle measures 66°, what is the measure of the consecutive angle if the trapezoid is isosceles?

Back

The consecutive angle measures 114°.

Front

What is the formula for the area of a trapezoid?

Back

Area = 1/2 * (b1 + b2) * h, where b1 and b2 are the lengths of the parallel sides and h is the height.

Front

How do you determine if a quadrilateral is a trapezoid?

Back

A quadrilateral is a trapezoid if it has at least one pair of parallel sides.

Front

What is the relationship between the bases of a trapezoid?

Back

The bases of a trapezoid are the two parallel sides.

Front

If the lengths of the bases of a trapezoid are 10 cm and 6 cm, and the height is 4 cm, what is the area?

Back

Area = 1/2 * (10 + 6) * 4 = 32 cm².

Front

What is a right trapezoid?

Back

A right trapezoid is a trapezoid with two right angles.
