Polyhedron - Wikipedia
In geometry, a polyhedron (pl.: polyhedra or polyhedrons; from Greek πολύ (poly-) 'many' and ἕδρον (-hedron) 'base, seat') is a three-dimensional figure with flat polygonal faces, straight edges and sharp corners or vertices. A convex polyhedron is a polyhedron that bounds a convex set.

What is a Polyhedron? Definition, Types, Parts, Formula, Examples
A three-dimensional shape with flat polygonal faces, straight edges, and sharp corners or vertices is called a polyhedron. Common examples are cubes, prisms, pyramids. However, cones, and spheres are not polyhedrons since they do not have polygonal faces.

2024年6月13日 · A polyhedron is a three-dimensional shape with flat polygonal faces, straight edges, and sharp vertices. Examples include cubes, prisms, and pyramids. However, shapes such as cones and spheres do not qualify as polyhedrons because they lack polygonal faces.
What is a Polyhedron - Definition, Types, Formula, Examples
A polyhedron is a 3D-shape consisting of flat faces shaped as polygons, straight edges, and sharp corners or vertices. A shape is named a polyhedron according to the number of faces it has. Ideally, this shape is the boundary between the interior and exterior of a solid.
