A parallelogram is a polygon with four vertices (quadrilateral), in which the opposite sides are pairwise parallel and equal to each other, as well as the opposite angles.

Thus, a parallelogram differs from a rectangle in that it has no right angles. By definition, a rectangle is a special case of a parallelogram.
