I expect to see a more elegant approach from pie's instructor, though, seeing how this is a rather... bullfighting method.

My teacher's solution is to draw line DF so that it is parallel to line BC, then connect F and B intersecting at point G. Then find isosceles and equilateral triangles (BGC and DFG and equilateral, CGE, BCE are isosceles) then prove that DEFG is a kite.
