Front

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

Back

To find the measure of an angle in a quadrilateral, use the formula: m∠A = 360° - (m∠B + m∠C + m∠D).

Front

What is the relationship between the angles in a parallelogram?

Back

In a parallelogram, opposite angles are equal, and adjacent angles are supplementary (sum to 180 degrees).

Front

What is the formula for the area of a rectangle?

Back

The area of a rectangle is given by the formula: Area = length × width.
