Luka Petrovic Posted February 21, 2013 Report Share Posted February 21, 2013 Is the diagram a set of circles with a line going through as a chord on the upper most circle and then the origin of the other two circles, with the vertices of the triangle going through the origins of the circles? (or centre, I can't remember my math terminology sorry!) Link to post Share on other sites More sharing options...
