If it is a pyramid, then the base shape is a SQURE. If it is a tetrahedron, then the base shape is a triangle.
It will be a square shape if it is a squared based pyramid
If the base of the pyramid is square, it must have four triangular vertical faces in order to meet at the apex (top). Such a 3D shape is a "square pyramid".
A square pyramid is a pyramid whose base is in the shape of a square.
a square based pyramid is a square at the bottom and a pyramid at the top
