WebBisector Definition. The bisector is a line that divides a line or an angle into two equivalent parts. The bisector of a segment always contains the midpoint of the segment. There are two types of bisectors based on what geometrical shape it bisects. Line Segment Bisector (Perpendicular Bisector Theorem) Angle Bisector (Triangle Bisector Theorem) personal finance software reviewWebWe know that BD is the angle bisector of angle ABC which means angle ABD = angle CBD. Now, CF is parallel to AB and the transversal is BF. So we get angle ABF = angle BFC ( alternate interior angles are equal).
