Polyhedron wikipedia
WebIn geometry, a polyhedron is a three-dimensional object with flat polygonal faces, sharp corners and straight edges. Each side is a flat surface and is without any curved surfaces. The word comes from the Greek 'poly' (stem of many) + 'hedron' (face). So, a polyhedron basically means 'many faced geometric shape.'. Web正多邊形多面體或稱正多邊形面多面體(Regular-faced Polyhedron)是指所有面都是正多邊形的多面體。 [18] 在三維空間中,所有面都是正多邊形不一定能滿足正多面體的定義,例如92種 詹森多面體 雖然所有面都是正多邊形但都不是正多面體。
