As dodecahedron and icosahedron are dual of each other , they can both arrive at the same football shape by truncation 切割十二面体及二十面体均可得到足球状的大球体。

As dodecahedron and icosahedron are dual of each other , they can both arrive at the same football shape by truncation 这称为正多面体的二重性。切割十二面体及二十面体均可得到足球状的大球体。

The dodecahedron ( 12 sided ) shaped object you see actually consists of 12 speakers which allow for non - directional 360 degree sound field 你看到的这个拥有十二面体形状的东西实际上由12个扬声器组成，可以制造360度的无方向性声场。

This form of construction is strong and has the additional advantage of enclosing a given volume with the least possible use of materials . geodesic domes are actually derived from regular polyhedra . those that are derived from the dodecahedron and the icosahedron have joints where 5 distinct triangles meet 由正十二或正二十面所建而成的短程线圆顶特色是当中的一些接驳点由五个三角形组成而由正八面体所建立的圆顶则可以分割成四分之一或四分之三个。
