Proposition

Circles O and Q intersect at A and B so that O is on circle Q (as shown in the figure). C is a point on circle O and OC extended cuts circle Q at D. The perpendicular bisector of CD cuts circle Q at G and H (G on arc AD, H on arc BD). E is a point on arc BC and OE extended cuts circle Q at F. The perpendicular bisector of EF cuts circle Q at M and N (M on arc AF, N on arc BF). Prove that lines CE, GN, and MH are parallel.
