PROOF Example

WebAn angle bisector is a line or ray that divides an angle into two congruent angles. The two types of angle bisectors are interior and exterior. Some important points to remember … WebWe 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). But we already know angle ABD i.e. same as angle …
