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:
Angle pairs deals with two angles. There are different types of angle pairs. Two angles which has one line in common is called as angle pairs. In angle pairs, the two angles are related to each other.These are complementary angle, supplementary angle, vertical angle, Alternate interior angles, Alternate exterior angles and Corresponding angles.ere, $\angle$ MOP is supplementary angle because, $\angle$ MON + $\angle$ NOP = 180 degrees. Vertical Angles: When two lines intersect each other, angle pairs are formed. In this type of angles, the angles in the opposite direction is said to be vertical angle.
