Making a tetrahedron

Introduction -- Making the Modules -- Making the Polyhedra -- Jim's Origami Page
The tetrahedron has four triangular faces that meet in groups of three at each of four vertices. It has six edges, and thus uses six identical triangle (tr--tr) modules.

When making the tetrahedron, the last module is usually difficult to get in. I usually color with 2 edges each of three different colors such that each triangular face is composed of edges of three different colors.

The resulting polyhedron is usually rock-solid.
