Spherical geometry or spherics (from Ancient Greek σφαιρικά) is the geometry of the two-dimensional surface of a sphere [a] or the n-dimensional surface of higher dimensional spheres.

Spherical geometry is the study of geometric objects located on the surface of a sphere. Spherical geometry works similarly to Euclidean geometry in that there still exist points, lines, and angles.

2025年1月20日 · The study of figures on the surface of a sphere (such as the spherical triangle and spherical polygon), as opposed to the type of geometry studied in plane geometry or solid …

AN INTRODUCTION TO SPHERICAL GEOMETRY A photographer goes out looking for bears. From her camp, she walks one mile due south, then one mile due east, where she …

Spherical geometry is defined as "the study of figures on the surface of a sphere" (MathWorld), and is the three-dimensional, spherical analogue of Euclidean or planar geometry.

Spherical geometry studies the surface of a unit sphere. This geometry has applications in cartography, navigation, and astronomy. The spherical geometry is a close relative of the …

We explore how geometry on a sphere compares to traditional plane geometry. We present formulas and theorems about the 2-gon and the 3-gon in spherical geometry. We end with an …

Spherical trigonometry is the branch of spherical geometry that deals with the metrical relationships between the sides and angles of spherical triangles, traditionally expressed using …

Planar geometry is sometimes called flat or Euclidean geometry. The geometry on a sphere is an example of a spherical or elliptic geometry. Another kind of non-Euclidean geometry is …

Spherical geometry is defined as the study of figures on the surface of a sphere, and it can be viewed as the three-dimensional version of Euclidean or planar geometry. Although closely …
