Well, that's true in two dimensions.  In three or four dimensions,
things become more complicated.  After all, think of meridian lines on
a globe-- they're parallel by many tests; yet they intersect at the
poles.  But then, you can draw a triangle on a globe whose internal
angles add to 270 degrees... on a curved surface or in a curved space,
geometry gets non-euclidean, and life gets funky.
