Answer:
Step-by-step explanation:
Since a parallelogram is parallel, it has 2 pairs of parallel sides. Opposite sides and opposite angles are congruent. Two pairs of opposite angles are equal in measure. The diagonals bisect each other. One pair of opposite sides is parallel and equal in length. Adjacent angles are supplementary. A parallelogram has two parallel pairs of opposite sides. A rectangle has two pairs of opposite sides parallel, and four right angles. It is also a parallelogram, since it has two pairs of parallel sides.
