It is a sphere
A sphere is a 3D circle. Like a baseball.
A 2d shape is a flat object (ex: square, circle, etc.) and a 3d shape is a shape in space (ex: cube, sphere, etc.)
Three dimensional shapes, generally, don't have lines of symmetry, but a circle has an infinite number is symmetry lines. 3D shapes also don't have rotational symmetry either, but a circle has an infinite number of that as well.
They are both round. They are both 3d. The 2d counterpart of both shapes is the circle.
It is a sphere
here are some: 2d shapes- square circle triangle Rectangle 3d shapes- cone cuboid cube prism
A sphere is a 3D circle. Like a baseball.
A 2d shape is a flat object (ex: square, circle, etc.) and a 3d shape is a shape in space (ex: cube, sphere, etc.)
It is because they all are 3D shapes
they look like geometry shapes that are 3D
3D shapes are three dimensional, just like 2D shapes are two dimensional.
It's a cylinder. Look at http://en.wikipedia.org/wiki/Cylinder_(geometry)

3D shapes have edges, sides, and intersecting points
The special features of 3D shapes are they all are 3D which means they are fat but 2D shapes are flat they can not stand up.
