Non Euclidean Geometry
Non-Euclidean Geometry is a mathematical system that diverges from the principles of Euclidean Geometry, introducing curved surfaces and non-parallel lines. It includes hyperbolic geometry, where there are multiple parallel lines through a single point, and elliptic geometry, where there are no parallel lines. Non-Euclidean Geometry is used to describe the geometry of curved spaces and is essential in modern physics and mathematics.
