The bisectors of the angles ABC and BCA of a triangle ABC meet in a point 0. What is the angle at O facing the side BC ?

If the bisector of an angle of a triangle bisects the opposite side,prove that the triangle is isosceles.

The internal angle bisector of an angle of a triangle divide the opposite side internally in the ratio of the sides containgthe angle

The external angle bisector of an angle of a triangle divides the opposite side externally in the ratio of the sides containing the angle.
