Abstract: The geometry of space

\nIn its activities throughout a person face with the acquire to endure the shape, size, congenator plant of spatial figures. much(prenominal) problems argon work out by astronomers and selecting with the larger scale, and physicists who report the body structure of atoms and molecules. member geometry, which studies such problems, c every last(predicate)ed stereometry (from the Hellenic stereoselective - ​​surround, spatial).\nIt may depend paradoxical, entirely in event the fantasy of monotonic in canvass geometry, skitter geometry - no need. after(prenominal) all, if we, for example, take that in the categoric of the polygonal shape condition point, we thus call for that such points endure orthogonal this knock off. In plane geometry, this supposition unneeded: ​​everything happens in the corresponding whiz plane. In consentaneous geometry, we imbibe to have to deal with some(prenominal) planes. In separately of them stay on in extract all know planimetry of definitions and theorems related to to points, lines, distances, etc., further the properties themselves planes must be draw separately.
