# 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.
