If the arms of one angle are respectively parallel to the arms of another angle, show that the two angles are either equal or supplementary.

Supplementary Angle

In the given figure,?1 and ?2 are supplementary angles.If ?1 is decreased,what changes should take place in ?2so that both the angles still remain supplementary.
