parallel->perpendicular, thanks to TonyK

Another wrinkle is that this method generates two values for the x-coordinate of the centroid, and you have to decide what to do when they are not equal due to rounding errors. Probably you should take the one that came from the 'least perpendicular' projection, i.e. the one with the greater area A. | |
