Also known as Platonic polyhedron
各面都是全等正多边形且每个顶点所接的面数均相等的凸多面体
A Platonic solid is a three-dimensional shape where all the faces are identical regular polygons and the same number of faces meet at every corner. These five special geometric forms—the tetrahedron, cube, octahedron, dodecahedron, and icosahedron—have fascinated mathematicians and scientists for centuries because of their perfect symmetry and their appearance in nature and art.

在幾何學中,凸正多面體,又稱為柏拉圖立體,是指各面都是全等的正多邊形且每一個頂點所接的面數都是一樣的凸多面體,是一種三維的正幾何形狀,符合這種特性的立體總共只有5種。在漢語文化中,正多面體通常是指只有5種的凸正多面體,然而在只討論每面全等、每個個角等角且每條邊等長的情況下,亦有其他多種幾何結構存在,也稱為正多面體。 正多面體的別稱柏拉圖立體是因柏拉圖而命名的。柏拉圖的朋友泰阿泰德告訴柏拉圖這些立體,柏拉圖便將這些立體寫在《蒂邁歐篇》(Timaeus) 內。正多面體的作法收錄《几何原本》的第13卷。在命題13描述正四面體的作法;命題14為正八面體作法;命題15為立方體作法;命題16則是正二十面體作法;命題17則是正十二面體作法。 * 正四面體 * 正六面體 * 正八面體 * 正十二面體 * 正二十面體
