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 9Solid angleNarrower topic: Solid-angle regions are spherical areas, so spherical geometry describes their shape.Great circleNarrower topic: Great circles serve as the spherical geometry’s counterpart to straight lines.Spherical trigonometryNarrower topic: Spherical trigonometry is the triangle-focused part of this broader geometry.Great-circle distanceNarrower topic: Great-circle distance is the spherical analogue of straight-line distance in a plane.Spherical law of cosinesNarrower topic: The law belongs to a geometry where straight paths are great-circle arcs.Spherical triangleNarrower topic: Spherical triangles are the basic polygonal figures of this geometry.Spherical excessNarrower topic: Spherical excess is a basic consequence of this geometry’s positive curvature.Square degreeNarrower topic: It supplies the surface-area relationships behind angular regions on the sky.
