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
When you draw a diagonal in a rectangle or a parallelogram, it divides the shape into two congruent triangles, meaning both triangles are the same size and shape. In contrast, drawing a diagonal in a trapezoid results in two triangles that can differ in size and shape, as the bases of the trapezoid are unequal. Thus, different size and shape triangles form only in the trapezoid.

it makes a dimond
Two triangles

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...
