Front

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

Back

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

Front

What is a trapezoid?

Back

A trapezoid is a quadrilateral with at least one pair of parallel sides.

Front

How do you find the missing angle in a trapezoid?

Back

To find the missing angle in a trapezoid, use the property that the sum of the interior angles is 360 degrees.

Front

What is a parallelogram?

Back

A parallelogram is a quadrilateral with opposite sides that are parallel and equal in length.

Front

What are the properties of a rectangle?

Back

A rectangle is a parallelogram with four right angles.

Front

What are the properties of a rhombus?

Back

A square is a quadrilateral that is both a rectangle and a rhombus, having four equal sides and four right angles.

Front

How do you calculate the missing angle in a quadrilateral?

Back

Subtract the sum of the known angles from 360 degrees to find the missing angle.

Front

What is the relationship between the angles in a trapezoid?

Back

In a trapezoid, the angles on the same side of a leg are supplementary (add up to 180 degrees).
