I would have asked this on a math community but I couldn't find an active one.
In a spherical geometry, great circles are "straight lines". As such, a triangle can have two or even three right angles to it.
But what if you go the long way around the back of the sphere? Is that still a triangle?
(Edit:) I guess it's a triangle! Fair enough; I can't think of what else you would call it. Thanks, everyone.

It's got three angles, so I'd say so
