Step1: Recall parallelogram properties

In a parallelogram, opposite sides are congruent by definition.

Step2: Recall angle - related properties

Opposite angles of a parallelogram are congruent. Also, consecutive angles of a parallelogram are supplementary (i.e., their sum is 180°), not congruent in general.
