This category contains pages concerning Angle Bisector Theorem:


Let $\triangle ABC$ be a triangle.

Let $D$ lie on the base $BC$ of $\triangle ABC$.


Then the following are equivalent:

$(1): \quad AD$ is the angle bisector of $\angle BAC$
$(2): \quad BD : DC = AB : AC$

where $BD : DC$ denotes the ratio between the lengths $BD$ and $DC$.
