The other name for Spherical Geometry is: A) Euclidean B) Plane Geometry C) non-Euclidean D) Normal

The correct answer is C) non-Euclidean. Spherical geometry is non-Euclidean because it does not follow Euclid's fifth postulate, also known as the parallel postulate. This postulate states that given a line and a point not on the line, only one line can be drawn through the point parallel to the given line. In spherical geometry, however, there are no parallel lines because all lines on a sphere eventually intersect. This fundamental difference from Euclidean geometry makes it a non-Euclidean geometry.
