The simplest solid with all triangular faces is a 'Tetrahedron'.

It is a triangular base , supporting three more triangles to a point.

It is sometimes wrongly confused with a pyramide.

From the Classical Languages

'Tetra' ; four

'Hedron' ; a solid shape.

The next solid is an 'hexahedron'. Six(6) triangular faces all 'back-to-back'. The next solid is an 'octahedron'. Eight(8) triangular faces all 'back-to-back'.
