A cylinder.
A 2d shape is a flat object (ex: square, circle, etc.) and a 3d shape is a shape in space (ex: cube, sphere, etc.)
A 3D star is not a standard shape. You can easily add another point.
Adding depth makes a 3D object from a 2D shape.
The edge of a 3D shape is called an "edge." It is the line segment where two faces of the shape meet. In geometric terms, an edge is one of the fundamental components that define the structure of polyhedra and other solid figures.
A geometric figure is a shape like a square or rectangle and it can be used in different views like 3D, 2D and 1D would be just a line. So there is your answer!

Polyhedra. AS long as the 3D shape has no curves

a megagon
No shape is mathematical really unless it has been created by a mathematical formula, but is certainly a geometric shape. But anything which is a 2D or 3D shape is geometric. My improvement: A catenary curve from a mathematical equation such as cosh x, is a mathematical and natural shape. Maby each other arch can be approximated by a mathematical formula.
A triangle is a geometric shape.
A triangular pyramid, also known as a tetrahedron, has four faces. This three-dimensional geometric shape is made up of four triangular bases.
The geometric shape of a shoebox is a rectangular prisim.
