In geometry, an octahedron is a polyhedron with eight sides. A regular octahedron is the dual polyhedron of a cube; It is a rectified tetrahedron.
The area of a regular octahedron with a side length of x is 2√3 * x²

A regular octahedron has 6 apexes as it can be rotated evenly as each face is congruent.
Octahedron- A polyhedron with eight faces. All faces of a regular octahedron are congruent, equilateral triangles.

The next of an octahedron looks like a series of 8 triangles.
octahedron is a regular square bipyramid but a square bipyramid can be non-regular
The faces of octahedra are triangles.
Sounds like an octahedron.

That's a really good question. It has several answers. You can put an octahedron through a square hole - just look at the octahedron point on.You can put an octahedron through a hole that's a regular hexagon - lay the octahedron down on a table on one of its triangles and look down on it and that's what you'll see.You can put an octahedron through a rhombus - to see that, look at it edge on. (This was the first answer posted to the question.)If you don't have a real octahedron to play with you can find one to rotate about with your mouse by visiting http://mathworld.wolfram.com/Octahedron.html

A regular octahedron is one of the platonic solids. Each of its faces is an equilateral triangle.
