Online Geometry Problem 795: Intersecting Circles, Common Chord, Midpoint, Tangent, Secant Line, Perpendicular, 90 Degrees. Level: High School, SAT Prep, College, Mathematics Education

The circles O and Q intersect at A and B (see the figure). M is the midpoint of AB and CAD is a secant line. The tangents at C and D meet at E. BF is perpendicular to CE and BG is perpendicular to DE. If FG cuts CD at H, prove that MH is perpendicular to FG.
