"Many sides". I.e Everything other than a line, or a circle/sphere.
The Greek word for polyhedron is "πολύεδρον" (polýedron), derived from "πολύς" (polús), meaning "many," and "ἔδρον" (édron), meaning "face." In geometry, a polyhedron is defined as a three-dimensional solid with flat polygonal faces, straight edges, and vertices. The term reflects the structure's characteristic of having multiple faces.
A polyhedron.
The word "hedron" comes from Greek, where it means "seat" or "base." It is commonly used in mathematics and geometry to refer to a three-dimensional polyhedron with flat faces and straight edges.
Because the Greek word polyhedron means many faces and the Greek word polygon means many sides
No because they have many faces which is the meaning of the word polyhedron
It is a Greek word meaning 'earth or land measurements'
In geometry, an octahedron is a polyhedron with eightfaces.
Geometry comes from a Greek word meaning 'earth measurement'
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.
If you want to make a 3d paper polyhedron there are some cut outs you can print from http://local.wasp.uwa.edu.au/~pbourke/geometry/polycuts/
Yes because it has many faces which is the meaning of a polyhedron
There are many special figures in geometry and some of them are pyramid, cone, cylinder, sphere, circle, prism, polygon, polyhedron ..... etc
