A square with a triangle on top forms a shape known as a "house" or "roof" shape. The base is the square, while the triangle serves as the roof, creating a structure that resembles a simple house design. This combination maintains the properties of both shapes, with straight edges and right angles in the square, and a pointed apex in the triangle.
