Complementary angles are two angles with a sum of 90Âº. Supplementary angles are two angles with a sum of 180Âº. Vertical angles are two angles whose sides form two pairs of opposite rays. We can think of these as opposite angles formed by an X. The Lesson:
Another special pair of angles is called supplementary angles. One angle is said to be the supplement of the other if the sum of their degree measurements is 180Â°. In other words, if we put the angles side by side, the result would be a straight line. Supplementary angles are angles whose sum is 180Â°.
