Circles W1,W2 intersect at P,K. XY is common tangent of two circles which is nearer to P and X is on W1 and Y is on W2. XP intersects W2 for the second time in C and YP intersects W1 in B. Let A be intersection point of BX and CY. Prove that if Q is the second intersection point of circumcircles of ABC and AXY
