Product Description
In this dynamic, engaging, discovery-based lab, students readily discover and prove the triangle-angle bisector theorem, which states that the angle bisector of one angle of a triangle cuts the side opposite that angle into segments that are in proportion to the triangle's other two sides.

The GeoGebra applet students use to discover (and help prove) this theorem can be found here: http://www.geogebra.org/material/simple/id/3114485
