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。
The icosahedron has the greatest number of faces , so it is the most common choice for making a geodesic dome 正二十面体是拥有最多面的柏拉图方体,所以它最常用于建造短线圆顶。
The icosahedron has the greatest number of faces ( 20 ) , so it is the most common choice for making a geodesic dome 正二十面体是拥有最多面的柏拉图方体,所以它最常用于建造短线圆顶。
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 20 - sided shape an icosahedron floats to the window and one of the 20 answers is visible , telling you the answer to your question 这个有着20个面的形状(一个20面体)浮到窗口上, 20个答案中的其中一个是可见的,告诉您问题的答案。
In order to improve the roundness of the icosahedron , its surfaces are divided into smaller ones and more points are raised to the surface of the sphere 为了令正二十面体的外形更接近球体,我们把它的面分解成更小的面,并将更多的端点升到球体表面。
After additional testing and analysis of several hundred dimpled configurations and shapes , the icosahedron pattern with 20 triangular regions was developed 在对几百种酒窝结构与形状进行了附加测试与分析之后,终于设计出一种二十面体的式样,其中每个面皆为三角形。

In geometry, an icosahedron ( or ) is a regular polyhedron with 20 identical equilateral triangular faces, 30 edges and 12 vertices. It is one of the five Platonic solids.
