Square Pyramid
The figure is a pyramid and the base is a square.
There is a contradiction in your question. If the base has four equal sides then is it a square so not all the faces are Triangles. However if the base is a square and the rest of the faces are triangles then your object is a "Square-based Pyramid"

pyramid. Base is a square, but each of the 4 sides is a triangle.
A solid figure with five faces is called a pyramid. Specifically, a triangular pyramid, or tetrahedron, has four triangular faces, while a square pyramid has one square base and four triangular faces, totaling five. The pyramid's faces meet at a single point called the apex.
A pyramid with a square base.
A square pyramid has a square base and four congruent triangular faces.
The 3D shapes that have all their faces equal to their base are known as regular polyhedra. Specifically, these include the tetrahedron (4 triangular faces), cube (6 square faces), octahedron (8 triangular faces), dodecahedron (12 pentagonal faces), and icosahedron (20 triangular faces). Each of these shapes features congruent faces that exhibit symmetry.
Not necessarily. The solid could be a square based cuboid (hexahedron).
