    Well, that's a property of parallelograms.

    But if you must prove it, I say you draw a diagonal from one angle to the opposite one, and then prove that the two triangles formed are congruent, since their three sides have the same length.

    After that, just prove that the opposite angles are congruent because correspondent angles on congruent triangles are congruent.. @BIGDOG96

    so here through this congruency it is proved that opposite angles of a parallelogram are always equal.

    Is there anyway you could write out the steps, they kinda got chopped off. @jiteshmeghwal9

    Is this right? First draw two bisectors in the parallelogram. So, here is a parallelogram namely ABCD. angle 5 = angle 4 alternate interior angles congruency. 1 - 2 - angle 6 = angle 3 alternate interior angles congruency. 3 -angle 1 = angle 8 alternate interior angle congruency. 4 - angle 2 = angle 7 alternate interior angle congruency.
