Given a circle centered at O, a point A is a pole and a line L is the corresponding polar if L is the line passing through the inversion of A with respect to the circle (see section 11.15.7) passing through the line OA.
The polar command takes as argument a circle C and a point a.
polar returns and draws the polar of the point a
with respect to C.
