In non-Euclidean geometry triangles on a sphere have?
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.

What is spherical geometry?
It is the geometry of a sphere as well as of shapes on the surface of the sphere.
Could triangles have right angles?
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).
When Compare and contrast Euclidean geometry and spherical geometry. Be sure to include these points 1. Describe the role of the Parallel Postulate in spherical geometry. 2. How are triangles differen?
Euclidean geometry is based on flat surfaces and includes the Parallel Postulate, which states that through a point not on a line, exactly one parallel line can be drawn. In contrast, spherical geometry operates on a curved surface where the concept of parallel lines does not exist; any two great circles (the equivalent of straight lines on a sphere) will intersect. In spherical geometry, triangles have angles that sum to more than 180 degrees, unlike in Euclidean geometry, where the angles of a triangle always sum to exactly 180 degrees. Thus, the fundamental properties and the behavior of lines and angles differ significantly between the two geometries.
What is elliptical geometry?
It's pretty much geometry on a sphere
What is a sphere or ball called?
Sphere is the term used in geometry.
Is there such thing as a triangle that's angles that don't up to 180?
Yes... and no.Triangles in Euclidian space, or a Euclidian plane - the kind usually considered in school - always add up to 180 degrees.However, other kinds of geometry have been invented, for example, triangles on a sphere. The "lines" that make up those "triangles" are the major circles - the sides of the triangles are thus the shortest distance between those points (along the surface of the sphere). It is interesting to note that the angle excess - the amount above 180 degrees - of such a triangle is directly proportional to the triangle's area.
