Angle Bisector Definition

In geometry, an angle bisector, also known as bisector of an angle, is a line that bisects or split an angle into two equivalent parts. In other words, a straight line drawn from the vertex that divides an angle into two same parts is known as an angle bisector.

For example, if the arms of an angle meet a vertex to form a 66 degree of angle, the line bisects an angle from mid form two different but the equivalent angle of 33 degrees.
