How come that after 55 or so years of involment with math this came as a big surprise !!!!!

Will you explain to me what is this theorem? It is hard to understand the whole concept by just looking/analyzing the figure. 🙂
Radical axis of 2 circles:
circles intersect, many circles through the two points of intersection, one of them is a straight line, this is the radical axis.
How to find it?
With equations, subtract one equation from the other one – magic, a straight line, and bset of all this works even when the two circles do not intersect.
