That is how it is defined: parallelograms have two sides that have congruent adjacent angles, so that the remaining two sides must be parallel and equal in length.

Parallelograms include rectangles (all right angles), squares (all right angles), rhomboids, and rhombi (the latter two have congruent but non-right angles, and a rhombus has 4 equal sides).
