8.3 Worksheet Proving Parallelograms Answer Key

What is a Parallelogram?

A parallelogram is a four-sided shape with two sets of parallel sides. The opposite sides of a parallelogram are of equal length and the opposite angles are of equal measure. Parallelograms are used to prove theorems in geometry and are important tools in many mathematical equations.

Proving Parallelograms

In order to prove that a figure is a parallelogram, one must use the properties of a parallelogram. These properties include: opposite sides are congruent, opposite angles are congruent, and consecutive angles are supplementary. In addition, if a parallelogram has four right angles, then it is a rectangle.
