Lesson 4 Properties of Kites and Isosceles Trapezoids

Front

What is a kite in geometry?

Back

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

Front

What are the properties of the diagonals of a kite?

Back

The diagonals of a kite are perpendicular to each other.

Front

How many pairs of congruent angles does a kite have?

Back

A kite has one pair of congruent angles.

Front

What is the relationship between the sides of a kite?

Back

A kite has two pairs of adjacent sides that are equal.

Front

What is an isosceles trapezoid?

Back

An isosceles trapezoid is a trapezoid with a pair of opposite sides that are parallel and the non-parallel sides are equal in length.

Front

What is the sum of the interior angles of a kite?

Back

The sum of the interior angles of a kite is 360 degrees.

Front

If AC = 44 in kite ABCD, what is EC?

Back

EC = 22 (since diagonals bisect each other in a kite).

Front

What is the measure of the angles in an isosceles trapezoid?

Back

The base angles of an isosceles trapezoid are equal.

Front

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

Back

Area = (d1 * d2) / 2, where d1 and d2 are the lengths of the diagonals.

Front

If the diagonals of a kite are perpendicular, what does this imply about the triangles formed?

Back

The diagonals divide the kite into four right triangles.
