In non-Euclidean geometry, specifically on the surface of a sphere, triangles have angles that sum to more than 180 degrees. This is contrary to the properties of triangles in Euclidean geometry, where the angle sum is always exactly 180 degrees. Additionally, the shortest path between two points on a sphere is along a great circle, which further influences the characteristics of spherical triangles. As a result, the shapes and relationships within triangles on a sphere differ significantly from their flat counterparts.
It is the geometry of a sphere as well as of shapes on the surface of the sphere.
Yes, although a triangle (in normal geometry) can only have one right angle, no more. It is possible for a triangle to have all three right angles in spherical geometry (if you were to draw the triangle on a sphere).
Sphere is the term used in geometry.

Well...... Actually, planes would be considered triangles in geometry because triangles are triangles.

It's pretty much geometry on a sphere
