In geometry, the angle bisector theorem is concerned with the relative lengths of the two segments that a triangle's side is divided into by a line that bisects the opposite angle. It equates their relative lengths to the relative lengths of the other two sides of the triangle. WebProblematic Start. The problem. Let AC and BD intersect at E, then E is the midpoint of BD. You can’t say E is the midpoint without giving a reason. Let M be the midpoint of BD, then let k be the line containing AMB, then by the theory of isosceles triangles, this line bisects angle BAC..
