Solid **geometry** is that subsection of geometry that deals with figures in three-dimensional **space**. Euclidean geometry, sometimes called parabolic geometry, is divided into two subsections: **plane geometry**, geometry dealing with figures in a plane, and solid geometry, geometry dealing with solids in three-dimensional space. Solid geometry is sometimes called three-dimensional Euclidean geometry and deals with solids, such as polyhedra and spheres, and lines and planes in three-dimensional space. Solid geometry is concerned with the study of figures in three-dimensional Euclidean space, which is usually denoted **R**^{3}.

Solid geometry is a branch of Euclidean geometry, developed by Greek mathematician Euclid in the 4th century B.C., that is governed by Euclid's five postulates as laid out in his work *The Elements*. More specifically the basics of solid geometry are described in Book XI of *The Elements*. Book XI consists of 28 definitions, in which Euclid departed from traditional...
