DescriptionAnim troncature icosaèdre.gif |
Français : Animation d'artiste de la troncature de l'icosaèdre formant un ballon de football. On voit comment la troncature de tous les sommets forme des pentagones. Cette troncature rognant aussi les triangle équilatéraux, il se forme des hexagones.
English: Artist animation of the truncation of the icosahedron forming a football. We see how the truncation of all vertices forms pentagons. This truncation also trims the equilateral triangle, hexagons are formed. |

Comme on le voit, la troncature de chaque sommet crée un pentagone, d'abord irrégulier puis régulier lorsque la troncature optimale est atteinte.
Ainsi qu'on le voit, chaque côté des pentagones épointe l'un des angles des triangles équilatéraux, ce qui transforme ces triangles équilatéraux en hexagones (d'abord irréguliers puis réguliers lorsque la troncature optimum est atteinte).
L'icosaèdre régulier de base est un solide régulier formé de 20 faces équilatérales identiques. Il comporte 12 sommets.
La troncature de ces 12 sommets forme 12 pentagones et 20 hexagones.
