a square based pyramid.
Well, any shape with a triangular face. I assume that you mean a shape that only has (identical) triangles for faces. There are 2: the tetrahedron with 4 triangles, and the icosahedron with 20 triangles. * * * * * What about a triangular dipyramid? Two triangular pyramids stuck together along one face?
The tetrahedron has 4 equilateral triangles as its faces.

A pyramid - it has a square base, and four triangles meeting to a point at the top.

A triangular prisim (3 faces on sides, one face on bottom).
A pyramid - it has a square base, and four triangles meeting to a point at the top.
square-based pyramid
4 faces are triangles and 1 face is a square the square face is the base of the pyramid
A net with three triangles is a two-dimensional representation that can be folded to form a three-dimensional shape. Specifically, this net could represent a triangular prism, where the three triangles form the two triangular bases and one rectangular face connecting them. When folded correctly, the net creates a solid where the triangular faces are opposite each other, and the rectangular face wraps around the sides.
