Organizing and summarizing search results for youA spherical plane refers to concepts in spherical geometry, where the basic elements are points and great circles, as opposed to straight lines in Euclidean geometry. In spherical geometry, great circles serve as the equivalent of straight lines, and any two great circles intersect at two points. This geometry is essential for understanding figures on the surface of a sphere, such as spherical triangles and polygons.2 Sources

In plane (Euclidean) geometry, the basic concepts are points and (straight) lines. In spherical geometry, the basic concepts are point and great circle. However, two great circles on a plane intersect in two antipodal points, unlike coplanar lines in Elliptic geometry. In the extrinsic 3-dimensional picture, a great … See more
