Angle Bisector Theorem
- Louisa Puffett
Use this app to investigate the concept that any point on an angle bisector is equidistant from both sides of the angle. Dragging point A will resize the angle. Notice what happens to the angle and segment measures. Dragging point B will move the point on the angle bisector. Notice what happens to the line segments.
What did you notice during your investigation. How might this apply to the three angle bisectors of a triangle?
