A pyramid perhaps
That would be a triangular pyramid.
A triangular prism can have a square or triangular base, but faces are normally triangles. (I think)
It depends on the shape of the base, but yes it has at least 3 triangular faces!(yes)
A tetrahedron.

Triangular Pyramid
The shape with a triangular base and three additional triangular faces is called a tetrahedron. It is a type of polyhedron that has four triangular faces, six edges, and four vertices. Tetrahedrons are one of the simplest three-dimensional shapes and are often studied in geometry and various scientific fields.
The 3D shape you are describing is a pentagonal pyramid. It has a pentagonal base with five sides, and five vertices where the triangular faces meet. The three rectangle faces are lateral faces that connect the triangular base to the apex of the pyramid. The pentagonal pyramid is a type of pyramid with a polygonal base and triangular faces.
The shape you are describing is a triangular pyramid. A triangular pyramid has a base that is a triangle and three triangular faces that meet at a single point called the apex. The base of the pyramid is a rectangle, which is a quadrilateral with four right angles. The triangular faces of the pyramid connect the vertices of the base to the apex.
