Define parallelogram and identify the characteristics that make a parallelogram special from just being a quadrilateral (opposite sides are parallel, opposite sides are congruent, opposite angles are congruent, consecutive angles are supplementary, diagonals bisect each other).
Provide examples that demonstrate how to use the characteristics of a parallelogram to solve for unknown variables, unknown side/diagonal lengths, and unknown angle measures.
This packet should help a learner seeking to understand the characteristics of parallelograms.
This video introduces the properties of parallelograms.
