New Geometry Video: Cube, Tetrahedron, Octahredron

As I detail at length in the book Basic Platonic and Archimedean Solids, there are many relationships between three of the Platonic solids: cube, tetrahedron, and octahedron. You can start with any of these shapes and perform a few simple "tricks" to get the other shapes.

Yesterday I created a new video to demonstrate one of these tricks: how to create a cube and use it to create tetrahedrons and an octahedron.



The detailed, written version of this project is included in April's Projects of the Month.
