KnowraSpherical geometryLinked fromLinked fromThe 30 pages that link to Spherical geometry, each with the reason it gives.All 30Broader topic 5Related 8Narrower topic 8Compared with 9Euclidean spaceCompared with: Its curved surface gives triangle angles and geodesics unlike Euclidean geometry.Hyperbolic geometryCompared with: It has positive curvature, contrasting with hyperbolic geometry’s negative curvature.Plane (geometry)Compared with: A sphere curves, so its surface is not a Euclidean plane.Triangle geometryCompared with: Spherical triangles have angle sums greater than 180 degrees, altering familiar relations.Euclidean planeCompared with: On a sphere, straightest paths and parallel behavior differ from those in the plane.Elliptic geometryCompared with: Unlike elliptic geometry, its spherical model keeps antipodal points distinct.Nikolai LobachevskyCompared with: It shows that changing Euclid’s parallel postulate can yield a different geometry, though not Lobachevsky’s.Playfair's axiomCompared with: Great-circle lines have no parallels, illustrating a model that violates the axiom.Hjelmslev's theoremCompared with: It offers a contrasting curved setting with different triangle angle and congruence behavior.
