Comment #2 on issue 2120 by smichr: Circle(Point(0.5, 0.2),Point(1.1,
0),Point(0.5, 0.5)) raise Except

Yes, you shouldn't use floating point with Geometry. To conver your points
to Rationals you could do something like this:
print Circle(*[S(str(p), rational=True) for p in
... (Point(0.5, 0.2),Point(1.1, 0),Point(0.5, 0.5))])
Circle(Point(53/60, 7/20), 610**(1/2)/60)
Ideally, you should be able to just put the whole expression as S('expr',
rational=True) but geometry isn't integrated well with sympy and doesn't
have an atoms method so an error is raised to that effect.
