A polyhedron, be definition, must be 3-dimensional. Therefore, there can be no such thing as a 2-d polyhedron
Can be. It would be the net of the polyhedron.
a 3d object made of 2d faces with all flat sides
An icosahedron is a polyhedron has 20 faces, and is a 3D shape.
A dodecahedron is a polyhedron with between 18 and 30 faces.
it is a term for a face , its different for all, if the polyhedron is based off a 2d polygon, it is the side with that shape(usualy)(their may be more than one)
Look at that shiny polyhedron! Oh yes, officer, I am quite certain that it was a blue and green polyhedron that crossed into the road.
Nevermind guys, I learned it in class today, our teacher doesn't inform us on homework very well...Anyways, you make a polyhedron rigid just like a 2d shape, where you add braces and form triangles. Just in this case, you do it on all sides not rigid, not just the one 2d shape.Thanks anyways!~xDragonx
polyhedron
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.
It is flat
A shape in 2D with n sides is called an n-gon. In higher dimensions, a shape with n sides is called an n-sided polyhedron.
