Theorem 4.4b: In an {n/k} star inscribed in a circle of radius r, if 1 < j < n/2 then the distance from the Pj points to the Pi points on a line of the star is
If the points are on the same side of Po use the minus sign. If they are on opposite sides, use the plus sign.
proof 1: We start with the formula from the previous result
