Read this definition I found this definition on Wolfram MathWorld:
A triangular pyramid is a pyramid having a triangular base.
The tetrahedron is a triangular pyramid having congruent
equilateral triangles for each of its faces.

Sean,
I keep making errors, in this case not an important one.A triangular pyramid is a pyramid having a triangular base.
The tetrahedron is a triangular pyramid having congruent
equilateral triangles for each of its faces.

Hanno,
I find Mr. Breed's method fascinating. I did indeed draw a copy of the diagram, cut it out and folded it into a perfect little tetrahedron. Neat. Thank you for posting this. If I ever run across a copy of that book, I'm buying it.
Regards,
Sean C.
