Nope Giggle up tetrahedron


Yes, it's a tetrahedron.

Since my mother worked in a library, she was exposed to a lot of
different pieces of information. She also got to use the copy machine
free, and often brought home copies of books or parts of books. One of
those was on "Platonic polyhedra", 3-dimendional shapes with all sides
the same 2-dimensional shape. There are five:

tetrahedron, 4 triangles
cube, 6 squares
octahedron, 8 triangles
dodecahedron, 12 pentagons
icosahedron, 20 triangles

I even know one 4-dimensional version: tesseract
