Comment(by strk):

 Sorry, I take "approximate equidistance from the center" back, in that any
 3 points _define_ the center. So the only left condition is the number of
 quadrant segments. Can help to avoid taking an L shape for a curve, but I
 suspect there'd be a lot more lines erroneously taken as curves. Hard
 problem
