Is octahedron a polyhedron?
In geometry, an octahedron (plural: octahedra, octahedrons) is a polyhedron with eight faces. The term is most commonly used to refer to the regular octahedron, a Platonic solid composed of eight equilateral triangles, four of which meet at each vertex.
How many faces edges and vertices does a polyhedron have?
These faces are regular polygons. Edge: the regions where the two flat surfaces meet to form a line segment are known as the edges. Vertex: It is the point of intersection of the edges of the polyhedron….Parts of a polyhedron.
| Name | No. of faces |
|---|---|
| Nonahedron | A polyhedron with 9 faces. |
| Decahedron | A polyhedron with 10 faces |
Does a polyhedron have vertices edges and faces?
A polyhedron is a three-dimensional solid made up of polygons. It has flat faces, straight edges, and vertices.
What are the faces of polyhedrons?
The faces of a polyhedron are its flat sides. The edges of a polyhedron are the edges where the faces meet each other. The vertices are the corners of the polyhedron.
How many faces does a polyhedron need?
A polyhedron is a three-dimensional solid with faces that are all flat. Because they are flat, all of the faces are polygons. Examples of polyhedra (the plural of polyhedron) include rectangular boxes, pyramids, and dodecahedra (i.e. polyhedra with 12 faces).
How many sides does polyhedron have?
There are only five regular polyhedra in the universe: the regular tetrahedron (which has four triangular faces), the cube (which has six square faces), the regular octahedron (which has eight triangular faces), the regular dodecahedron (which has 12 pentagonal faces ), and the regular icosahedron (which has 20 …
Can a polyhedron have 7 edges?
No simple polyhedron has seven edges.
How many faces edges and vertices does a octahedron?
Any object in real life has vertices, faces and edges. For example, a crystal is an octahedron – it has eight faces, twelve edges and six vertices.
How many faces does octahedron?
8Octahedron / Number of faces
How much faces does octahedron have?
8 faces
The word octahedron is derived from the Greek word ‘Oktaedron’ which means 8 faced. 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.
What is a vertices of a polyhedron?
A point at which three or more polyhedron edges of a polyhedron meet. The concept can also be generalized to a polytope.
How many vertices are in the polyhedron?
There are 4 faces, 6 edges and 4 vertices. This solid is also a polyhedron.
What polyhedron has 8 edges?
Regular Octahedron

| Regular Tetrahedron | 4 | 6 |
| Cube | 6 | 12 |
| Regular Octahedron | 8 | 12 |
| Regular Dodecahedron | 12 | 30 |
What polyhedron has 7 faces?
A heptahedron is a polyhedron with seven faces. There is a single “regular” heptahedron, consisting of a one-sided surface made from four triangles and three quadrilaterals.
Can a polyhedron have 10 faces?
Hence, a polyhedron cannot have 10 faces, 20 edges and 15 vertices.
