All shapes can be classified into two types, what are they called and define them

All shapes can be classified into 3D and 2D types.

3D- Three-dimensional model that displays a picture or item in a form that appears to be physically present with a designated structure. Essentially, it allows items that appeared flat to the human eye to be display in a form that allows for various dimensions to be represented. These dimensions include width, depth, and height.

2D- A shape with only two dimensions (such as width and height) and no thickness. Appears flat to a persons eyes.
