How many edges do a octahedron have?
12 edges
More generally, an octahedron can be any polyhedron with eight faces. The regular octahedron has 6 vertices and 12 edges, the minimum for an octahedron; irregular octahedra may have as many as 12 vertices and 18 edges.
How many sides per face does a octahedron have?
8 faced
Once joined the shape converts to 8 faced, 12 edges, and 6 vertices. An octahedron is most commonly known as the regular octahedron i.e. when all the faces are of the same shape and size….Octahedron.

How many rectangular faces does a octahedron have?
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.
How many nets does a octahedron have?
There are 11 distinct nets for an octahedron, the same number of nets as for a cube, see Figure 17. All nets have eight triangular faces.
How many sides does a dodecahedron have?
twelve faces
From left to right the solids are tetrahedron (four sides), cube (six sides), octahedron (eight faces), dodecahedron (twelve faces), and icosahedron (twenty faces).
What is an example of octahedron?
Octahedral molecular geometry describes the shape of compounds wherein six atoms or groups of atoms or ligands are symmetrically arranged around a central atom. The octahedron has eight faces, hence the prefix octa-. An example of an octahedral compound is molybdenum hexacarbonyl (Mo(CO)6).
How many edges does a cone have?
An edge is where two faces meet. A vertex is a corner where edges meet….Vertices, edges and faces.

What is a pentagon in 3d called?
A three-dimensional shape that includes pentagons is a regular dodecahedron. A regular dodecahedron has 12 sides.
Does Cone have an edge?
Lead students to see that a cone has no edges (at least no straight ones!), but the point where the surface of the cone ends is called the vertex of the cone. Although a cylinder has two faces, the faces don’t meet, so there are no edges or vertices.
How many edges does a cuboctahedron have?
In geometry, a cuboctahedron is a polyhedron with 8 triangular faces and 6 square faces. A cuboctahedron has 12 identical vertices, with 2 triangles and 2 squares meeting at each, and 24 identical edges, each separating a triangle from a square.
How many edges does a nonagonal pyramid have?
A nonagonal pyramid. To be a prism with 10 vertices, you must have a pentagonal prism, with 5 vertices at each base. But this prism would have 15 edges: 5 at each base and 5 between the bases.
How many vertices and edges does an icosahedron have?
An icosahedron is a regular polyhedron with 20 faces, all of which are equilateral triangles. An icosahedron has 30 edges and 12 vertices.
How much does tetrahedron edges have?
A tetrahedron is a polyhedron with 4 faces, 6 edges, and 4 vertices, in which all the faces are triangles. It is also known as a triangular pyramid whose base is also a triangle. A regular tetrahedron has equilateral triangles, therefore, all its interior angles measure 60°.
