This looks like an easy bug to fix. The code line in question is this:
return (inter is not None and isinstance(inter[0], Point)
and len(inter) == 1)
where, clearly, we should be checking len(inter) == 1 *before* we try to look at inter[0]. I'll make a patch to reverse those two tests and then it should work. Thanks for the report.

Description of problem: ellipse construction problem in computational geometry Version-Release number of selected component (if applicable): sympy-0.7.5-1.fc20.noarch How reproducible: every time Steps to Reproduce: 1. run sympy: python from sympy import * 2. enter command Circle(Point(5,5), 3).is_tangent(Circle(Point(0,5),1)) Actual results: Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/usr/lib/python2.7/site-packages/sympy/geometry/ellipse.py", line 771, in is_tangent return (inter is not None and isinstance(inter[0], Point) IndexError: list index out of range Expected results: False Additional info: the expression is working fine for other values of the second circle radius: Circle(Point(5,5), 3).is_tangent(Circle(Point(0,5),3)) returns False Circle(Point(5,5), 3).is_tangent(Circle(Point(0,5),2)) returns True
