dodecahedron n.(pl. dodecahedrons, -dra )...

dodecaphonic

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線圓頂特色是當中的一些接駁點由五個三角形組成;而由正八面體所建立的圓頂則可以分割成四分之一或四分之三個。

The dodecahedron ( 12 sided ) shaped object you see actually consists of 12 speakers which allow for non - directional 360 degree sound field 你看到的這個擁有十二面體形狀的東西實際上由12個揚聲器組成,可以制造360度的無方向性聲場。

As dodecahedron and icosahedron are dual of each other , they can both arrive at the same football shape by truncation 這稱為正多面體的二重性。切割十二面體及二十面體均可得到足球狀的大球體。
