Answer:

If a pair of opposite sides of a quadrilateral are parallel and equal, then it is a parallelogram.

Explanation:

By definition, a parallelogram is a quadrilateral with two pairs of parallel sides. These parallel sides are of equal length and the opposite angles of a parallelogram are of equal measure.
