Notes 6-2 properties of parallelograms - A Parallelogram is a flat shape with opposite sides parallel and equal in length. Opposite sides are parallel. Opposite sides are equal in length. Opposite angles are equal (angles A are the same, and angles B are the same) Angle A and angle B add up to 180°, so they are supplementary angles. Play with a Parallelogram:

 
Properties of Parallelograms: If a quadrilateral is a parallelogram, then: *Its opposite sides are congruent. *Its opposite angles are congruent. *Its consecutive angles are supplementary. *Its diagonals bisect each other.
