## Angle bisector theorem proof | Special properties and parts of triangles | Geometry | Khan Academy - Free Educational videos for Students in k-12

#### DESCRIPTION:

In this video, we'll quickly review the angle bisector theorem, and then we'll see how it's proven. We prove it by extending a parallel line to one of the triangle's legs. That tells us information about the interior angles!
