Summary

[edit]
Description
English: The convex hull of a “small stellated dodecahedron” or a “great dodecahedron” is a Platonic icosahedron. In other words, the polygonal stellations of the convex pentagonal faces of a Platonic dodecahedron have the twelve vertices of a convex regular icosahedron. Conversely, we can construct a Platonic dodecahedron by truncating a Platonic icosahedron on each vertex, each cross section containing five edges of the initial icosahedron.
Français : L’enveloppe convexe d’un “petit dodécaèdre étoilé” ou d’un “grand dodécaèdre” est un icosaèdre de Platon. Autrement dit, les étoilements polygonaux des faces pentagonales convexes d’un dodécaèdre de Platon ont les douze sommets d’un icosaèdre régulier convexe. Inversement, on peut construire un dodécaèdre de Platon en tronquant un icosaèdre de Platon à chaque sommet, chaque section contenant cinq arêtes de l’icosaèdre initial.
