Trapezoids and Kites

Front

What is a trapezoid?

Back

A trapezoid is a four-sided figure (quadrilateral) with at least one pair of parallel sides.

Front

What is an isosceles trapezoid?

Back

An isosceles trapezoid is a trapezoid in which the non-parallel sides are equal in length.

Front

What are the properties of the base angles in an isosceles trapezoid?

Back

The base angles of an isosceles trapezoid are congruent.

Front

How do you find the midsegment of a trapezoid?

Back

The midsegment of a trapezoid is the average of the lengths of the two bases: Midsegment = (Base1 + Base2) / 2.

Front

If EH = 4x - 27 and FG = x + 9, how do you solve for x?

Back

Set the expressions equal to each other if EH and FG are the bases of an isosceles trapezoid and solve for x.

Front

What is the formula for the area of a trapezoid?

Back

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

Front

What is a kite in geometry?

Back

A kite is a quadrilateral with two distinct pairs of adjacent sides that are equal.

Front

What are the properties of the diagonals in a kite?

Back

In a kite, one diagonal bisects the other diagonal at a right angle.

Front

How do you find the length of a diagonal in a kite?

Back

Use the Pythagorean theorem if the lengths of the sides and the angle between them are known.

Front

What is the relationship between the angles in a kite?

Back

The angles between the unequal sides of a kite are equal.
