If the two angles share one side and a vertex, the point where two lines meet in an angle, the angles are called adjacent. The sides that are not shared form a straight angle which is 180 degrees in measurement. Two angles are still considered supplementary even if the angles are not adjacent. As long as the total of the degree measurements is 180 degrees, then the angles are supplementary.
