Circumcircle of triangle
Hi everyone there.
I've got a question I cannot solve. Can anyone of you tell me its answer ??(Headbang)
In a figure, D is a point on circumcircle of triangle ABC in which AB=AC. If CD is produced to E such that BD = CE then prove that AD=AE.

Major hint: Prove that the triangles ABD, ACE are congruent.
