what are the parts of a polyhedron?

polyhedron (pŏl'ēhē'drən) , closed solid bounded by plane faces; each face of a polyhedron is a polygon. A cube is a polyhedron bounded by six polygons (in this case squares) meeting at right angles. Although regular polygons are possible for any number of sides, there are only five possible regular polyhedrons, having congruent faces, each a regular polygon and meeting at equal angles. The five regular polyhedrons are also known as the Platonic solids, although they were known to the Greeks before the time of Plato. They are the tetrahedron, bounded by four equilateral triangles; the hexahedron, or cube, bounded by six squares; the octahedron, bounded by eight equilateral triangles; the dodecahedron, bounded by twelve regular pentagons; and the icosahedron, bounded by twenty equilateral triangles. The 18th-century Swiss mathematician Leonhard Euler showed that for any simple polyhedron, i.e., a polyhedron containing no holes, the sum of the number of vertices V and the number of faces F is equal to the number of edges E plus 2, or V+F=E+2

a 20 faced polyhedron is called an \nicosahedron-the faces are equilateral\ntriangles\na 20 sided polygon is called an\nicosagon\n\ni hope that this helps

An octahedron is a regular solid with eight identical faces. Octahedral coordination of a metal occurs when six bonded atoms of coordinating ligands occupy sites that would correspond to the six vertices (corners) of a regular octahedron surrounding the metal atom.

Make a Dodecahedron. That's what I did.

Division 1, Division 2 and Division 3.\n\nKidding, i think the base, handle and the eyepiece/nose piece.\nNot sure though.

6 faces, 12 edges, 8 vertices

Its only a cube if all the edges are the same length (and of course the sides are perpendicular).  What you're referring to is a right-angled parallelepiped.\n\nIt's a cuboid ONLY if a pair of sides are squares.  If all the sides are rectangles, it's a right-angled parallelepiped.\n\nA regular polyhedron is a polyhedron with all the sides the same.

a polygon with 5 sides is a pentagon.\n\nthis has two right angles so it would look like the picture of a basic drawing of a house.   see the pic of the house attached.\n\nhttp://www.thestationerystudio.com/index.cfm/fuseaction/catalog.viewProduct/productId/5214

I'm afraid that with the given information, this would be impossible to determine. The only thing one could conclude from this information is that this polygon has an even number of sides. \n\nIt could be a square with sides of 3cm each\nIt could be a hexagon with sides of 2cm each\nIt could be an octagon with sides of 1.5cm each\nIt could be a decagon with sides of 1.2cm each\nIt could be a 12-gon with sides of 1cm each\n\nThe list is infinite unless you are given more specific information, such as the length of each side or the angles within the shape.

The number of vertices in this polyhedron is exactly 8.\nAccording to Euler's Theorem, (number of vertices)-(number of edges)+(number of faces)=2 for all polyhedrons.

A two dimensional figure is called a dodecagon and a 3D figure with 12 sides is called a dodecahedron.
