Comparison and contrast The Polyhedron and polygons are closely related, as noted above, the Polyhedron __s__ are formed by face or polygons, but the Polyhedrons are three-dimensional objects and the polygon __s__ __a__ two-dimensional object, that is, the Polyhedron ha__ve__ has width, length and height while polygons only have width and length. In the polygons the sides built it while in polyhedral to these sides are called with edge and identifies the faces of three-dimensional figure. Both figures vertices have the same function. Something interesting, is that the duality is present in the two cases, duality is that inside of one convex figure can be generated another convex figure. For example.

Classification.

The polyhedrons can be classified in many groups, according __to the characteristics that distinguish; according to their characteristics, are distinguished:__ ( It is a little repetitive )

Convexes polyhedrons, as the cube, or the tetrahedron, when any pair of points of the space are within the body unites a segment of straight also. In the case that this segment was exit the body are said to be polyhedrons concave Polyhedron faces regular, when all sides of polyhedron are regular polygons. Polyhedron faces uniforms, when all sides are equal. It said polyhedron of edges uniform when in all its edges meet the same number of faces. Polyhedron of vertex __uniform__ when in all the vertices of polyhedron converge the same number of faces and in the same order. Polyhedron regular or regulate and uniform, as the tetrahedron or the icosahedrons, when it faces regular, faces uniforms vertex uniforms and edges uniforms

Hemmdersito: Nice work !!! =) but you should review all the corrections !!!
