The following sentence is not true. It's true for hyperbolic geometry, but not elliptic geometry.

The parallel postulate is the only postulate of Euclidean geometry which fails for non-Euclidean geometry.

[edit] Pedantic Note

It's a bit of a nitpick, but theorems aren't "proved". They're "proven". Saying that a theorem is "proved" rather than "proven" is like saying that a toaster is "broke" rather than "broken".--Flarity 06:14, 23 October 2006 (UTC)
