A tetrahedral die (not dice!) is a triangle-based pyramid, whose four faces are equilateral triangles.
Small numbered tetrahedron dice are commonly referred to as "d4" dice. The term "d4" signifies that the die has four faces, each numbered from 1 to 4. These dice are often used in tabletop role-playing games and other gaming scenarios.
Some roleplaying game die and puzzles such as the Rubik's Cube are shaped like tetrahedrons.

A tetrahedron has 4 faces.
Imagine a pyramid, with a triangle shaped base, with three sides coming up each of which is a triangle. That is a tetrahedron (4 sides, all the same side, with each one the shape of a triangle). * * * * * Mostly correct, but the four faces need not all be the same.
A tetrahedron must be plane faced and so, it is just an ordinary tetrahedron.
