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:
