In Euclidean geometry, a parallelogram is a simple (nonselfintersecting) quadrilateral with two pairs of parallel sides.

The congruence of opposite sides and opposite angles is a direct consequence of the Euclidean parallel postulate and neither condition can be proven without appealing to the Euclidean parallel postulate or one of its equivalent formulations.
