Length of the internal bisector of a triangle
Description
An angle bisector of a triangle is a straight line through a vertex which cuts the corresponding angle in half. The three angle bisectors intersect in a single point, the incenter, the center of the triangle’s incircle.There is a relation between the length of the internal bisector, opposite to the side “a” and the sides of the triangle. (Also equivalently for bisectors Wb and Wc).
