Any triangular structure. The triangle is used in building structures like towers and bridges because the three sides of a triangle, when locked together at their ends, are very strong and do not change shape. It's one of the most important shape in constructions. The circle is another important shape too.
It is a 2D shape
2D - the triangle 3D - the tetrahedron (i.e. it has a triangle on each side and there are 4 sides.
It's a 2D shape.
this is the shape of 2d cone
it a triangle as a 2d shape

A rhombus is a 2D shape.
2d
this is the shape of 2d cone
Nevermind guys, I learned it in class today, our teacher doesn't inform us on homework very well...Anyways, you make a polyhedron rigid just like a 2d shape, where you add braces and form triangles. Just in this case, you do it on all sides not rigid, not just the one 2d shape.Thanks anyways!~xDragonx

2d
it a triangle as a 2d shape
The answer is zero. A 2D shape has no volume.
A 2D shape does have one face.
