There are four faces.
0, a triangular pryamid (or tetrahedron) is made up of four triangular faces.
There is only one net to a triangular pyramid.
A triangular based pyramid has 4 faces (1 for the base, and one from each side to the other vertex), meaning the net will have 4 sections - one for each face.
Net of the Triangular Prism
A net for a triangular pyramid is made out of 4 triangles. A net for a triangular prism is made out of 3 rectangles and 2 triangles.
base is triangular
Triangular prism: 2 triangles, 3 rectangles Triangular pyramid: 4 triangles.
Four.
A square-based pyramid has 2 nets. One net consists of a square base and four triangular faces, while the other net includes the same square base and four triangular faces arranged differently. These nets can be folded to form the three-dimensional shape of a square-based pyramid.

A tetrahedron (a triangular pyramid) has these properties. But I'm not sure what you mean by show the net.
