Illusions are “figures which appear to be other than they really are”.

Types of illusions

Ambiguous Figures Distortions Fictions Paradox

An ambiguous figure is a figure that can be interpreted in more than one way, so the brain is not sure what to make of it.

Fictions

These illusions cause us to see things that are not true.

A paradox is something that may appear ridiculous but is actually true. These illusions are also called impossible figures because they are impossible. If you tried to make these into real (3D) objects you would not be able to.
