# Length of internal bisector of an angle in triangle in relation to the opposite segments

## Description

In geometry, bisection is the division of something into two equal or congruent parts, usually by a line, which is then called a bisector. If the internal bisector of an angle in a triangle divides the side opposite that angle into two segments, then the length of the bisector can be calculated by the lengths of the segments and the lengths of the other two sides of the triangle.
