2D is "flat", using the horizontal and vertical (X and Y) dimensions, the image has only two dimensions and if turned to the side becomes a line. 3D adds the depth (Z) dimension. This third dimension allows for rotation and visualization from multiple perspectives.
Why is it called 2D?
2D shapes are shapes with two dimensions, such as width and height. An example of a 2D shape is a rectangle or a circle. 2D shapes are flat and cannot be physically held, because they have no depth; a 2D shape is completely flat.
Who discovered 3D shapes?
History. The Pythagoreans dealt with the regular solids, but the pyramid, prism, cone and cylinder were not studied until the Platonists. Eudoxus established their measurement, proving the pyramid and cone to have one-third the volume of a prism and cylinder on the same base and of the same height.

What are 3D Shapes?
What makes something 3D? Is it the way it looks? An easy way to think of a 3D shape is any shape or object that takes up air space. Think about your own body for a minute. Your body is a 3D shape. It is not a uniform shape, like a building block, but it is a 3D shape, nonetheless. What makes your body a 3D shape? Does it take up air space? Of course it does; you can't be at the same spot as anyone else. You can't take up the same space as a chair or a dog or anything else. Only you can occupy your space. This is what makes a shape 3D.

Three-dimensional shapes have many attributes, such as vertices, faces, and edges. The flat surfaces of the 3D shapes are called the faces. The line segment where two faces meet is called an edge. A vertex is a point where three edges meet.
What are Three-Dimensional Shapes?
Shapes that can be measured in 3 directions are called three-dimensional shapes. These shapes are also called solids. Length, width, and height (or depth or thickness) are the three measurements of three-dimensional shapes. These are the part of three-dimensional geometry. They are different from 2D shapes because they have thickness. Several examples can be found in everyday life. Some of them are:
