Square Pyramid
The 3D shape made up of 4 triangles and 1 square is a square pyramid. It has a square base and four triangular faces that converge at a single point, known as the apex. The triangular faces are the lateral sides of the pyramid, while the square forms the base.

To find the base of a figure, you first need to identify the shape of the figure. The base of a figure is typically the bottom or lower side that forms the foundation or support for the rest of the shape. For example, in a triangle, the base is usually the side on which the triangle stands. In a rectangular prism, the base is one of the two parallel and congruent rectangular faces.
That would be a pyramid. A square (or rectangular) base where a line rises up from each corner of the square at an equal degree less than 90o and meet at a point above the center of the square. All four sides will be triangular.
