Bisector (bisectrix) of triangle
$$l = \sqrt {b\cdot c-m\cdot n}$$
l - length of bisector
b, c - triangle sides
m, n - lengths of the two segments that a triangle's side is divided into by a bisector
b, c - triangle sides
m, n - lengths of the two segments that a triangle's side is divided into by a bisector
