Excercise 40 Prove that the pairwise radical axes of three circles with not collinear centers meet a сотmоn pоint. Hint. Equalities 0,p² – r} = O2P2 – rž and O,P2 – r = O3P? – r imply that O1P² – r? = O3P² – r, i.e. the intersection point of the radical axes l12 and l23 is on l13 as well. It is called the radical center of the circles.
Let f1 be reflection with respect to the y-axis and let f2 be counterclockwise rotation through π/2 radians. Show that the result of first performing f2 and then f1 is not the same as first performing f1 and then performing f2.
