An octahedron has 18 corners.
An octahedron is a polyhedron with eight faces. A regular octahedron can be composed of eight equilateral triangles, four forming each half, and meeting in the middle at a square. Imagine a pyramid, with a square base. Rising up from each edge is an equilateral triangle that meets the other four triangles at the apex. Now, turn the pyramid over and add four more triangles to the other side the same way. You now have an octahedron. For more information, and a rotating picture, please see the related link below.
In geometry, an octahedron is a polyhedron with eightfaces.
An octagon is 2-dimensional, an octahedron is 3-dimensional.
An octahedron is a closed 3-d shape with 8 polygonal faces. There are 257 topologically different convex octahedra. An octahedron can have 6 to 12 vertices.
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 faces of octahedra are triangles.
It look like two square based pyramids stuck together on their square sides.
You start with a quadrilateral based bipyramid, which has six vertices. At each vertex, remove the tip in the form of a quadrilateral based pyramid. You will be left with a truncated octahedron.
1. My house (really). 2. Another 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
An octahedron is a closed 3-d shape with 8 polygonal faces. There are 257 topologically different convex octahedra. The simplest octahedron to make is probably the heptagon based right pyramid. The net for this shape is a regular heptagon with seven identical triangles attached to its edges. If the triangles are folded to meet at a point above the heptagonal base you will have an octahedron.
look on youtube they explain it their name is i heart oragami
I think you mean OCTAHEDRON. An Octahedron is an 8-sided solid object. It is like two pyramids placed bottom to bottom.
A weirdly cut jello?
An octahedron has 8 sides.An octahedron is a polyhedron with eight plane faces.
An octahedron has eight faces. If it has 62 faces then it is not an octahedron!
