It could be a cone
the shape that can make two smaller triangles is parallelogram.
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.
Triangular prism
Same size and shape
A net that forms a triangular prism consists of two triangular faces and three rectangular faces. The triangular faces serve as the bases of the prism, while the rectangular faces connect the corresponding sides of the triangles. When folded along the edges, the rectangles connect the two triangles to create the three-dimensional shape of the prism.

Two triangles
it makes a dimond

The two triangles would make either a square or a rectangle.
All of them.
draw a rectangle and two triangles on top
Two triangles can but its an irregular shape
Two triangles,two rectangles
Those would be SIMILAR triangles.
A triangular prism, where the two ends are triangles.
There are quite a few. Circles, squares, triangles...
