Olympiad Geometry Problem #4: Butterfly Theorem

This is my first video of a well-known theorem in geometry rather than a competition problem. It is very beautiful. Hope you enjoy!

I saw that angles in same segment were equal. I even took diametrically opposite points in hope of getting congruent triangles. Then stupidly, I missed it! Uff...

I wanna know, is reverse of theorem true too? I mean let MX=MY and M midpoint given, prove EF and HG intersect at M. And is there shortcut to prove this?
