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. The term "polyhedron" may refer either to a solid figure or to its boundary surface.

Polyhedron is a 3D shape with flat polygonal faces, straight edges, and sharp corners or vertices. Learn the definition, types, formulas, examples, and more. Parents

A polyhedron is a three-dimensional solid shape with a certain number of faces, edges and vertices. In this article, you will learn polyhedron definition, types, formulas and examples in detail. The word polyhedron has several meanings imperceptibly in geometry and algebraic geometry.

A polyhedron is a solid shape with flat faces and straight edges. Each face is a polygon (a flat shape with straight sides). Polyhedron comes from Greek poly- meaning "many" and -hedron meaning "face".

2023年8月3日 · A polyhedron (plural – polyhedra or polyhedrons) is a 3-dimensional shape consisting of polygons joined at their edges. A polyhedron has no curved face. Its components are the multiple polygon-shaped flat faces.

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. How Do You Identify a Polyhedron?

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 hedron (seat).

2025年2月21日 · 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 exterior of a solid.

A polyhedron is a three-dimensional (3D) solid figure that is made up of only polygons, meaning that the figure has no curves. 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 number of faces they have.

A polyhedron is a three-dimensional (3D) shape with flat faces. A regular polyhedron has: Otherwise it is irregular. The 5 Platonic Solids are all regular polyhedra. A regular polyhedron has: Faces that are identical regular polygons. the same number of faces meet at each vertex (corner).
