Webradius: [noun] a line segment extending from the center of a circle or sphere to the circumference or bounding surface. WebAn isometry of the sphere is a mapping of the sphere to itself which preserves the distance between points. It is easy to see that a rotation of the sphere around one of the sphere's diameters is an isometry. It simply rotates the picture to the left into another one just like it, but in a different plane. hhtyWebSecondly, the line can intersect the sphere in only one point.

WebMar 17, 2024 · In differential geometry, spherical geometry is described as the geometry of a surface with constant positive curvature. There are many ways of projecting a portion of a sphere, such as the surface of the Earth, onto a plane. These are known as maps or charts and they must necessarily distort distances and either area or angles.
