Equal circles 2, Initial position
- Ryan Hirst
Two unequal circles can be projected to equal ones. I use the same projection as in the Arbelos problem (http://www.geogebratube.org/material/show/id/54557 ). The bounding circle of the figure has become a line. A good way to solve a general problem is to start with a particular case. Here, I begin with the initial position: the circle tangent to - two tangent circles of equal radii -a straight line tangent to both.
