You do not. You see it stereoscopically, but the brain compares the images with experience and assumes threedimensional interpretations. This can be used to fool people with optical illusions. Forms that are possible in a twodimensional world, but does not have a representation in 3D that makes sense.

Yes forms usually are either organic or geometric. Organic shapes resemble shapes usually met in nature; the gentle curve of a tree branch, the floral or a rock for example. Geometric shapes are easy to draw and measure with rulers and other devices. Usual geometric shapes are symmetric like circle, square, triangle, cross... for example. Geometric shapes can also be asymmetric.
