Octagonal prism
Octagonal prism?
Eight - that is why it is called an octagon.
An octagon has has 8 corners.
The flat shape (2-D) is an octagon. An eight-sided solid is an octahedron.
Octagonal prism
A 3-dimensional shape with eight sides is an octahedron. If you would refer to a 3-dimensional octagon, just call it that, people will understand what you mean. Or maybe you mean an octagonal prism. That's an octagon, except it is extended into the third dimension by stretching it, so it has an octagonal base but the other sides are triangles all connecting at one point above the octagon.
Octagonal prism?
Simply that: "irregular octagon".
If its 2-dimensional then its an octagon, if it is 3-dimensional then it is called an octahedron.
Octagon. * * * * * An octagon is 2-dimensional. The regular 3-d shape (all faces the same) is the octahedron, but a hexagonal prism also has 8 faces.
Eight - that is why it is called an octagon.
An octagon has has 8 corners.
Yes, an eight-sided figure is called an octagon.
The flat shape (2-D) is an octagon. An eight-sided solid is an octahedron.
An octagon pyramid is more properly called an octagon-based pyramid. It is a 3-dimensional object whose base is an octagon. Attached to each side of the octagon are triangles whose bases are exactly the same lengths as the corresponding sides of the octagon. The "free" vertices of these triangles meet at a point, the apex, in a plane above the base.
Eight sided shape is called octagon.
