## Essay (Polyhedra)

### by Jason Marvin

I have learned a number of things about the polyhedra. For example, this is a tetrahedron:

It has a total of 4 faces and its face shape is a triangle:
It has 6 vertices and 4 edges.

For another example we used the World Wide Web to look at a home page that Mrs. Alejandre made for her students. On that home page their were many example of polyhedra. My partner found a page that gave the edges, vertices, faces and face shapes of all the different kinds of polyhedra. That page had an example of many polyhedra partners that were similar to them.

We as a class have studied six kinds of polyhedra including a cube, tetrahedron, octahedron, dodecahedron, icosahedron and cuboctahedron. We learn how to find the edges, vertices, faces and the face shape of each and every one of these solid shapes. We learned by reading our textbook, by listening in class, by using KaleidoTile software and using the Web.

One of the first things that we did was go into a program called KaleidoTile. This program has a number of different geometric prisms and polyhedra. One of the other things that we did was to construct the six polyhedra that we had learned about out of paper so that we could see the faces, vertices, edges and the face shape of them. When we used the World Wide Web my partner and I found two things that we could not understand which Mrs. Alejandre helped us learn to pronounce.

One was a word, rhombitruncated icosadodecahedron, and the other was the notation En= and then it would have a long number after it like 46.455828. Once of the other things we found on the Internet was a description of polyhedra. It showed the number of vertices, edges and faces for that particular polyhedra. When we used KaleidoTile that program showed us all the different polyhedra and the different dimensions of those shapes. We also used KaleidoTile so that we could get a better perspective of the shape.
