The diameter of the sphere which passes through the center of the circle is called its axis and the endpoints of this diameter are called its poles. A circle of a sphere can also be defined as the set of points at a given angular distance from a given pole. See more A circle of a sphere is a circle that lies on a sphere. Such a circle can be formed as the intersection of a sphere and a plane, or of two spheres. Circles of a sphere are the spherical geometry analogs of generalised circles See more In the geographic coordinate system on a globe, the parallels of latitude are small circles, with the Equator the only great circle. By contrast, all meridians of longitude, paired with their … See more • Line-plane intersection • Line–sphere intersection See more When the intersection of a sphere and a plane is not empty or a single point, it is a circle. This can be seen as follows: Let S be a sphere with center O, P a plane which intersects S. Draw OE perpendicular to P and meeting P at E. Let A and B be any two different … See more • Sykes, M.; Comstock, C.E. (1922). Solid Geometry. Rand McNally. pp. 81 ff. See more WebA sphere is a three-dimensional solid consisting of all points that have the same distance from a given center C. This distance is called the radius r of the sphere. You can think of a sphere as a “three-dimensional circle ”. Just like a circle, a sphere also has a diameter d, which is twice half the length of the radius, as well as chords ...
