What Compare and contrast the major characteristics of euclidean and non euclidean geometry?

Answer 1

Euclidean geometry is based on the principles outlined by Euclid, emphasizing flat spaces and relying on postulates such as the parallel postulate, which states that through a point not on a given line, exactly one parallel line can be drawn. In contrast, non-Euclidean geometry arises when this parallel postulate is altered, leading to geometries such as hyperbolic and elliptic geometry, where multiple parallels can exist or none at all. While Euclidean geometry deals with shapes and figures in two-dimensional flat planes, non-Euclidean geometry explores curved surfaces and spaces, resulting in different properties and relationships among points, lines, and angles. Overall, the key distinction lies in the treatment of parallel lines and the nature of space itself.
