... Supplementary Angles and Complementary Angles Two angles that form a line are supplementary angles. Another term for these angles is a linear pair. However, any two angles with measures that sum to 180 are also considered supplementary angles. In both figures below, m1 = 120 and m2 = 60, so 1 and ...
