A square based pyramid.
A pyramid with a square base.
No, a square pyramid is not a polygon; it is a three-dimensional geometric figure. A polygon is a flat, two-dimensional shape with straight sides, such as a triangle or a square. In contrast, a square pyramid has a square base and four triangular faces that converge at a point above the base, giving it volume and depth.

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"

The figure is a pyramid and the base is a square.
A three dimensional triangular figure with three faces and a base is called a triangular pyramid. It has four vertices, four faces, and six edges.
