Octahedron - Wikipedia
In geometry, an octahedron (pl.: octahedra or octahedrons) is a polyhedron with eight faces. One special case is the regular octahedron, a Platonic solid composed of eight equilateral triangles, four of which meet at each vertex. Regular octahedra occur in nature as crystal structures.

An octahedron is a polyhedron with 8 faces, 12 edges, and 6 vertices and at each vertex 4 edges meet. It is one of the five platonic solids with faces that are shaped like an equilateral triangle. Learn more about Octahedron with this article.
Octahedron - Math.net
A regular octahedron has 8 congruent faces that are congruent equilateral triangles, 12 congruent edges, and 6 vertices; an edge is a line segment formed by the intersection of two adjacent faces; a vertex for a regular octahedron is a point where 4 edges meet.
Octahedron – Definition, Properties, Formulas, & Diagrams
2023年11月27日 · An octahedron is a polyhedron. It has eight faces, twelve edges, and six vertices. If we join two square pyramids at their bases, we can create a regular octahedron. It belongs to the family of five platonic solids. Octahedron-shaped diamonds, ornaments, dice, and Rubik’s cubes are some real-life examples of an octahedron.
Regular Octahedron -- from Wolfram MathWorld
The regular octahedron, often simply called "the" octahedron, is the Platonic solid with six polyhedron vertices, 12 polyhedron edges, and eight equivalent equilateral triangular faces, denoted 8{3}. It is illustrated above together with a wireframe version and a net that can be used for its construction.
Faces, Edges and Vertices of an Octahedron - Neurochispas
Octahedrons are three-dimensional shapes made up of eight triangular faces. These geometrical shapes are one of the five Platonic solids. Octahedra have 8 faces, 12 edges, and 6 vertices. Four faces of the octahedron meet at each vertex. Here, we will learn more about the faces, vertices, and edges of octahedrons.

2024年11月18日 · The regular octahedron, often simply called "the" octahedron, is the Platonic solid with six polyhedron vertices, 12 polyhedron edges, and eight equivalent equilateral triangular faces, denoted . It is also uniform polyhedron and Wenninger model . It is given by the Schläfli symbol and Wythoff symbol.
Octahedron - Simple English Wikipedia, the free encyclopedia
An octahedron is a polyhedron made of eight faces. In the case of the regular octahedron, these faces are triangles. The octahedron looks like two pyramids, which share the same base. Dice: The one in the middle is an Octahedron. In chemistry, octahedra are common: diamonds and fluorite are examples of crystals that are octahedra.
Octahedron - Meaning, Properties, Solved Examples and FAQs
Face. The octahedron consists of 8 faces, which are all in the shape of equilateral triangles. These 8 faces are where the solid attains its name. 'Octa' means 8. These faces form the surface area of the octahedron. The square which is the base of the octahedron is not part of the surface area; hence, the base isn't also a face. Base
