The cross section, of a 3D object, is the 2D shape made when a 2D plane cuts across the 3D object. Often "cross section" refers to the shape made when the plane is at right angles to an axis of the 3D object but this need not be the case.
There is no 2D shape that makes a sphere, since a sphere is 3D by definition. The closest thing to a 2D sphere is a circle.
You cannot have a 2d pyramid - whether or not it is square based. The 2d cross section will depend on the plane of the cross section.
A 2 dimensional shape (or a 2D shape) is a shape withe a length and height, in some other cases, like a circle or oval or irregular shapes are also 2D shapes. Conclusion: A 2D shape is a shape that only have one section, that can be drawn.
It's a 2D shape.
You cannot have a 2d cylinder. The 2d cross section will depend on the plane of the cross section.
