The presence of a lone pair decreases the bond angle between the bonding pair of electrons, due to their high electric charge which causes great repulsion between the electrons. They are also used in the formation of a dative bond.
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.
