As dodecahedron and icosahedron are dual of each other , they can both arrive at the same football shape by truncation 切割十二面體及二十面體均可得到足球狀的大球體。
The icosahedron has the greatest number of faces , so it is the most common choice for making a geodesic dome 正二十面體是擁有最多面的柏拉圖方體,所以它最常用于建造短線圓頂。
The icosahedron has the greatest number of faces ( 20 ) , so it is the most common choice for making a geodesic dome 正二十面體是擁有最多面的柏拉圖方體,所以它最常用于建造短線圓頂。
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。
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 這個有著20個面的形狀(一個20面體)浮到窗口上, 20個答案中的其中一個是可見的,告訴您問題的答案。
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 為了令正二十面體的外形更接近球體,我們把它的面分解成更小的面,并將更多的端點升到球體表面。
After additional testing and analysis of several hundred dimpled configurations and shapes , the icosahedron pattern with 20 triangular regions was developed 在對幾百種酒窩結構與形狀進行了附加測試與分析之后,終于設計出一種二十面體的式樣,其中每個面皆為三角形。

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.
