U6L6 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

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

Back

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

Front

What is the relationship between the base angles of an isosceles trapezoid?

Back

The base angles of an isosceles trapezoid are congruent.

Front

What does it mean for angles to be supplementary?

Back

Two angles are supplementary if the sum of their measures is 180 degrees.

Front

What is the definition of congruent angles?

Back

Congruent angles are angles that have the same measure.

Front

What is the significance of the diagonals in a kite?

Back

In a kite, the diagonals are perpendicular to each other.

Front

How do you find the value of x in a trapezoid?

Back

To find the value of x, use the properties of trapezoids, such as the relationships between angles and sides.

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 bases and h is the height.

Front

What is a kite in geometry?

Back

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