  1. Will you explain to me what is this theorem? It is hard to understand the whole concept by just looking/analyzing the figure. 🙂

  2. 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.

My wordpress emails suddenly disappeared last night ??????
