## Properties of Parallelograms

rhombus- a parallelogram with four congruent sides

rectangle - a parallelogram with four right angles

square- a parallelogram with four congruent sides and four right angles

## Trapezoid and Isosceles Trapezoid Example

Each pair of base angles are congruent (angle C and angle F) (angle D and angle E).

This means that if angle C equals 65 degrees than angle F must equal 65 degrees.

So, 180 - angle C =115. Angle D and angle E equal 115 degrees.
