These are sometimes called ''acute'' or ''prolate'' and the ''obtuse'' or ''oblate'' golden rhombohedron. The rhombic triacontahedron is constructed with 30 golden rhombic faces, alternating 3 and 5 around every vertex. The dihedral angle between adjacent rhombi of the rhombic triacontahedron is 144°, which can be constructed by placing the short sides of two golden triangles back-to-back. The rhombic icosahedron is also constructed with golden rhombi. :120px150px The nonconvex rhombic hexecontahedron can be constructed by 20 ''acute golden rhombohedra''. It also represents a stellation of the rhombic triacontahedron. : 120px 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「Golden rhombus」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.
