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.

    Why the down votes? Bro asking a question and being legit curious, don’t be hating on someone that’s looking to challenge what they know just because it’s trivial to you.

      I feel my comment adds to the discussion and wants more details.
      But it was too simply phrased.
      I guess the details of such a question should be obvious. And if you need the details, the question doesn’t actually add the the discussion… It just seems idiotic!

      I felt like there might be a really cool scenario where a vertice isn’t considered a vertice.
      Like, there actually might be some case on a 2d plane “where actually” applies.
      I’m fine being wrong
