Polyhedron comes from Greek poly- meaning "many" and -hedron meaning "face". The plural can be polyhedra or polyhedrons. What faces does it have? No curved surfaces: cones, spheres and …

Real world examples of polyhedra include the Great Pyramid of Giza, concrete blocks, dice, bricks, and more. Polyhedrons are made up of faces, edges, and vertices. They are named based on the …

In geometry, a polyhedron is simply a three-dimensional solid which consists of a collection of polygons, usually joined at their edges. The word derives from the Greek poly (many) plus the Indo-European …

Polyhedron, In Euclidean geometry, a three-dimensional object composed of a finite number of polygonal surfaces (faces). Technically, a polyhedron is the boundary between the interior and …

The meaning of POLYHEDRAL is having the form of a polyhedron : having many faces. How to use polyhedral in a sentence.

Let us learn more about the types of polyhedrons and solve a few examples to understand the shape better. A polyhedron is a three-dimensional solid made up of polygons. It has flat faces, straight …

Regular polyhedrons are made up of regular polygons. They are also known as “Platonic solids.” They have all their faces, edges, and angles congruent.

Jul 23, 2025 · A polyhedron is a 3D solid made up of flat polygonal faces, with edges meeting at vertices. Each face is a polygon, and the edges connect the faces at their vertices. Examples include …

Polyhedral compounds are formed as compounds of two or more polyhedra. These compounds often share the same vertices as other polyhedra and are often formed by stellation.
