# Angle Bisector

## Angle Bisector

Line that divides an angle into two congruent angles.

### Examples

• In this illustration, line d is the bisector of angle A :

If $$m< 1=m< 2$$, then line d is the bisector of angle A.
If d is the bisector of angle A, then $$m< 1=m< 2$$

• In the triangle ABC below, the three bisectors $$\overleftrightarrow{AM}$$, $$\overleftrightarrow{BN}$$ and $$\overleftrightarrow{CP}$$ converge at the same point, which is equidistant from each side of the triangle:
