In drawing an example of how a center finder works, I drew a right triangle with an hypoteneuse of 6" and an altitude of 5.5". The Pythagorian Theorem says that the third leg should conform to the formula, (aa) + (bb) = (c*c). I’ve done the math in a calculator program and got he result, 2.3979"; however, SU gives a dimension of 2.4260" for a difference of 0.0281."
Now, that is close enough among friends, but I don’t understand the discrepancy. The attached file shows the results. You will notice that the hypoteneuse length is actually 6.0001" in SU, but one ten-thousandth of an inch shouldn’t cause a difference of that magnitude (or ‘minitude’ ).
I suspect that there is an error in my drawing that I cannot discover. I would appreciate extra eyes looking at the drawing and/or an explanation of the error. On a scale of inches, it really isn’t significant; but it certainly would be with a much larger scale.
