      OP thinks this is weird because in Euclidean geometry the sum of all internal angles in a triangle should add up to 180 degrees, but this is spherical geometry so the same rules don't apply.

      Not all, its just non-euclidian geometry, nothing to worry about. The stuff you learn at school, about triangles, and geometry and shit, only applies when the planes are "striaght". When these planes are curved (like the surface of a sphere is) then some of these rules change - i.e. a triangles angles no longer add up to 180...
