2. Parallelograms
Definition: Quadrilateral with two pairs of opposite parallel sides.
Properties:
Opposite angles are congruent
Both pairs of opposite sides are congruent
Diagonals bisect
Sum of interior angles is 360 degrees
Consecutive angles are supplementary
One pair of opposite sides are parallel and congruent

3. Parallelograms (continued)
Examples of Properties
Opposite angles
are congruent
Diagonals bisect
Opposite sides congruent and parallel

4. Rectangles Definition: A parallelogram with 4 right angles Properties:
