Best ResponseYou've already chosen the best response.0By the definition of angle bisector, angles ABD and CBD are congruent. Also, segment BD is congruent to itself. dw:1433095209819:dw

Best ResponseYou've already chosen the best response.0yes you can... and what mathstudent55 is right. You have to draw a line in the middle... call it D and using the theorems and definitions you can prove that the triangles are congruent.
