4. The angle bisectors of a triangle concur (meet) at a point called the incentre (I). Line segments AF, CE and BD are the angle bisectors of triangle ACB. Students often, incorrectly, believe that an angle bisector also bisects the side opposite the angle Show that BD does not bisect side AC. Note: use two letter names (ie AE) for sides and three letter names (ie. ZBAC) for all angles when doing this question. CA=1474 cm E AB=9.81 cm CB-19 13 cm H
