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 are the properties of an isosceles trapezoid?

Back

An isosceles trapezoid has congruent non-parallel sides, congruent base angles, and its diagonals are congruent.

Front

How do you find the sum of the interior angles of a trapezoid?

Back

The sum of the interior angles of any quadrilateral, including a trapezoid, is 360°.

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 a kite?

Back

A kite has one pair of opposite angles that are equal, and its diagonals intersect at right angles.

Front

If the diagonals of a trapezoid are congruent, what type of trapezoid is it?

Back

If the diagonals of a trapezoid are congruent, it is an isosceles trapezoid.

Front

What is the formula for the area of a trapezoid?

Back

The area of a trapezoid is given by the formula: Area = (1/2) * (b1 + b2) * h, where b1 and b2 are the lengths of the parallel sides and h is the height.

If AC = 44 in kite ABCD, what is EC if E is the midpoint of AC?

Back

EC = 22, since E is the midpoint.

Front

What is the relationship between the angles in an isosceles trapezoid?

Back

In an isosceles trapezoid, the base angles are equal.

Front

How do you find the measure of an angle in a trapezoid?

Back

To find the measure of an angle in a trapezoid, use the properties of the trapezoid and the sum of angles, or apply the exterior angle theorem.
