A triangle and a square
the answer is pyramid
A net for a square pyramid can be formed using one square and four triangular shapes. The square represents the base of the pyramid, while the triangles serve as the lateral faces that connect at the apex. When arranged correctly, the triangles can be attached to the edges of the square, allowing the net to fold into the three-dimensional shape of the pyramid.
A square-based pyramid net consists of a square base with four isosceles triangle faces extending from each side of the square. The triangles meet at a single point at the top of the pyramid. When the net is folded and assembled, it forms a three-dimensional square-based pyramid shape.
you draw a square with equilateral triangles on each side.
The net you are referring to is called a square pyramid net. It consists of four triangular faces and one square base. When the net is folded along its edges and assembled, it forms a three-dimensional square pyramid shape.
You cannot have a 2d pyramid - whether or not it is square based. The 2d cross section will depend on the plane of the cross section.
4 triangles and 1 square.
A square based pyramid.
The net of a square pyramid consists of a square base and four triangular faces. When laid out flat, the square base is at the center, and the four triangles extend outward from each side of the square. This arrangement allows for the pyramid to be constructed by folding the triangles up to meet at a point above the base.
One square and four triangles.
