Parallelograms - Geometry

This geometry video tutorial provides a basic introduction into parallelograms. It explains the properties of parallelograms and how to use it calculate the missing sides and missing angles of parallelograms. It contains plenty of examples and practice problems for you to work on. Opposite sides of a parallelogram are parallel and congruent. The diagonals bisect each other into congruent segments. Opposite angles are congruent and same side interior angles are supplementary.
