This category contains pages concerning Length of Angle Bisector:
Let $\triangle ABC$ be a triangle.
Let $AD$ be the angle bisector of $\angle BAC$ in $\triangle ABC$.
Let $d$ be the length of $AD$.
Then $d$ is given by:
- $d^2 = \dfrac {b c} {\paren {b + c}^2} \paren {\paren {b + c}^2 - a^2}$
where $a$, $b$, and $c$ are the sides opposite $A$, $B$ and $C$ respectively.
