definition of angle bisector
ray that divides an angle into 2 congruent angles
An angle bisector is a line or ray that divides an angle into two congruent angles. It begins at the vertex of the angle and extends to the interior of the angle. The angle bisector divides the angle into two equal parts, with each part measuring half of the original angle. It is named as such because it divides the angle into two parts that have the same measure or bisects the angle. The angle bisector is often used in geometry for constructing lines and geometric figures, as well as in trigonometry and other math applications.
