There are only five geometric solids that can be made using a regular polygon and having the same number of these polygons meet at each corner.
The five Platonic solids (or regular polyhedra) are the tetrahedron, cube, octahedron, dodecahedron, and icosahedron. History of Platonic Solids The five regular polyhedra were discovered by the ancient Greeks. The Pythagoreans knew of the tetrahedron, the cube, and the dodecahedron; the mathematician Theaetetus added the octahedron and the icosahedron. These shapes are also called the Platonic solids, after the ancient Greek philosopher Plato; Plato, who greatly respected Theaetetus' work, speculated that these five solids were the shapes of the fundamental components of the physical universe. Platonic Solids - Info Note: Euler's formula states that (The Number of Faces) + (The Number of Vertices) - (The Number of Edges) = 2 Printable Worksheets and Activities Click to read our Privacy Policy Advertisement.
Geometry Construction Reference. This guide was originally written for my own geometry students.
These instructions can be found in most elementary geometry books, but it might be more convenient to have them all in one place, rather than scattered throughout the book. Compass and straightedge construction can be far more complex, but I have no intention of adding to this work. These are the basics. Use them as tools to build an understanding of higher concepts. What is construction? About the instruments. Word Version - If you plan on printing this guide, it will look much better in the original format, which was done on Word 97.
