Since a dodecahedron has a circumradius divided by edge length greater than one,〔 sqrt(sqrt(5))/8 ) = 1.401259〕 so the pentagonal pyramids can not made with regular faces. The dual to the dodecahedral pyramid is a icosahedral pyramid, seen as an icosahedral base, and 12 regular tetrahedral meeting at an apex. : == References== 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「Dodecahedral pyramid」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.
