An angle bisector in a triangle divides the opposite side into two segments which are in the same proportion as the other two sides of the triangle. |
An angle bisector of an angle of a triangle divides the opposite side in two segments that are proportional to the other two sides of the triangle. Reciprocal of the bisector theorem: If a point D inside the side BC divides it into segments that respect the relation BD / CD = AB / AC, then AD is the bisector of the angle A. |
