Polyhedron 3d shape
WebVideo transcript. What we're going to explore in this video are polyhedra, which is just the plural of a polyhedron. And a polyhedron is a three-dimensional shape that has flat surfaces and straight edges. So, for example, a cube is a polyhedron. All the surfaces are flat, and all of the edges are straight. So this right over here is a polyhedron. WebA regular polyhedron is a polyhedron whose faces are all congruent, regular polygons. A regular polyhedron is named based on its number of faces. There are only five polyhedra that are regular polyhedra; these are referred to as Platonic solids. The five Platonic solids. In the diagram above, each regular polyhedra is named based on its number ...

In geometry, a polyhedron (plural polyhedra or polyhedrons; from Greek πολύ (poly-) 'many', and εδρον (-hedron) 'base, seat') is a three-dimensional shape with flat polygonal faces, straight edges and sharp corners or vertices.
