Given concentric circles C1 and C2, centered at ), and point A exterior to C1 but interior to C2 as shown, construct an equilateral triangle AXY, such that X is on C1 and Y is on C2 (Hint: How can you introduce a 60 degree angle?)
Remember your method should be analytically correct not merely visually apparent. Just finding a triangle that looks like it's probably equilateral doesn't count
