In three-dimensional Euclidean space, it is degenerate if its faces are flat, while in three-dimensional spherical space, a dihedron with flat faces can be thought of as a lens, an example of which is the fundamental domain of a lens space L(''p'',''q''). Usually a ''regular dihedron'' is implied (two regular polygons) and this gives it a Schläfli symbol as . Each polygon fills a hemisphere, with a regular n-gon on a great circle equator between them.〔Coxeter, ''Regular polytopes'', p. 12〕 The dual of a ''n''-gonal dihedron is the ''n''-gonal hosohedron, where ''n'' digon faces share two vertices. ==As a polyhedron== A ''dihedron'' can be considered a degenerate prism consisting of two (planar) ''n''-sided polygons connected "back-to-back", so that the resulting object has no depth. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Dihedron」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
