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:
Any two angles are called Supplementary angles when they add up to 180Â°. When two angles add to 180Â°, we say that the angles are âSupplementâ to each other. In the pair of supplementary angles if one angle is xÂ°, then its supplement is an angle of (180 - x)Â° .
