Does a right triangle have three right angles?

Not in traditional, 2 dimensional, euclidean geometry, because a triangles angles always equal 180º .However, there is a branch of Geometry that deals with a coordinate system on a sphere, instead of a plane, and in spherical geometry a triangle with three right angles is very much possible. Consider, for example, the triangle bounded by the Prime Meridian, 90o west longitude, and the equator.

How many degrees are a sphere?

It has the same degrees as a circle 360 degrees.

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).

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.
