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.

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.
