Kites & Trapezoids Review

Front

What is an isosceles trapezoid?

Back

An isosceles trapezoid is a quadrilateral with one pair of parallel sides and the non-parallel sides (legs) that are equal in length.

Front

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

Back

True

Front

If AC = 6x + 2 and BD = 4x + 8 in an isosceles trapezoid, how do you solve for x?

Back

Set the expressions equal: 6x + 2 = 4x + 8, then solve for x.

Front

What is the length of AC when x = 3 in the isosceles trapezoid?

Back

AC = 6(3) + 2 = 20.

Front

What is the formula for finding the length of the midsegment in a trapezoid?

Back

The midsegment length is the average of the lengths of the two bases: (Base1 + Base2) / 2.

Front

Find the measure of the midsegment if the bases are 20 and 10.

Back

Midsegment = (20 + 10) / 2 = 15.

Front

What is the property of the diagonals in a kite?

Back

The diagonals in a kite are perpendicular to each other.

Front

True or False: The diagonals of a kite bisect each other.

Back

False, the diagonals of a kite do not bisect each other.

Front

What is the measure of x if the angles in a kite are 90 degrees?

Back

x = 45 degrees.

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.
