Re: arc or curve fitting program

Yes, but the "math" equivalent of that geometric "construction"
technique is unwieldy, as one has to find distances, slopes, and
inverse slopes, midpoints, etc.

The algebraic equation is simpler by a long stretch...

P.S. The "perpendicular bisector" algorithm WILL come up in the first
few hits of a yahoo search on "three point circle"
