Two-dimensional shapes are shapes that are flat on the page, such as a square, circle, rectangle, triangle, etc. In contrast, some examples of three-dimensional shapes are cube, sphere, prism, pyramid, etc.
4 rectangles / Correction: two triangles.
triangular pyramid and cube.
You can make a square, a rhombus, a parrallelogram, a kite, a rectangle, and a trapezoid. If you were to make all these shapes out of two triangles, you would have to have different sized triangles for most of them. If you put the bottoms of both of them together, it will make a diamond shape. But they would have to be the same size.

Two equilateral triangles.
4 rectangles / Correction: two triangles.
A polygon with n sides, and n triangles, where n ≥ 3. Most commonly, the polygon at the base is a triangle or a square. If the base polygon is regular and the pyramid is a right pyramid (ie apex above the centre of the basal polygon), the triangles will be isosceles.
