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!

This lesson covers the median of a triangle. Students learn the definitions of a median of a triangle, an altitude of a triangle, and a perpendicular bisector. Students are then asked to identify or draw medians, altitudes, and perpendicular bisectors in given triangles.

Skip ahead to :18 to see another sample problem worked through. This time we're using the angle bisector theorem. Don't be confused by the word "ray" here -- she means the "bisector" or "line segment." Remember: bisect = cut in half.
