2d, or two demensional
3 demensional
the 2 demensional is flat and the 3 demensional shape is like a cube(it is popped out).

A triangle is not a polyhedron. A triangle is a two-dimensional figure, and a polyhedron is a three-dimensional solid. An example of a triangular-shaped polyhedron is a pyramid.
It is a polyhedron with two congruent faces: nothing more, nothing less. That can change if several additional conditions are required of the polyhedron.
