MHB Proving Miquel's Theorem: Need Help!

[pholee95]

I don't know how to start proving this theorem, so can someone please help? I need to prove that the circumcircles all intersect at a point M. Thank you!

Miquel's Theorem: If triangleABC is any triangle, and points D, E, F are chosen in the interiors of the sides BC, AC, and AB, respectively, then the circumcircles for triangleAEF, triangleBDF, and triangleCDE intersect in a point M.

I have attached here the figure of theorem.

Have you looked at https://en.wikipedia.org/wiki/Miquel's_theorem? The trick seems to be to take $M$ to be the point where two of the three circles meet, draw the lines $MD$, $ME$ and $MF$, then use properties of cyclic quadrilaterals to show that $M$ also lies on the third circle.
