Angle Bisectors, Medians, Perpendicular Bisectors of a Triangle
1. Move point A until line m, line l and segment AD coincide. 2. Record AB and AC. 3. Move point A to two other places in which line m, line l and segment AD coincide. On a separate sheet of paper, record the results for AB and AC. 4. What can you conclude about ΔBAC when the angle bisector of <BAC, the median from A to segment BC, and the perpendicular bisector of segment BC coincide?
