Linear perspective is a type of perspective that combines several concepts into one technique that creates one of the most convincing illusions of depth within a two-dimensional work. It is also one of the most scientific approaches to communicating this illusion. The basic principle is that lines converge to a vanishing point. In one point perspective there is only one vanishing point, as seen in this work by Leonardo da Vinci.
Another part of linear perspective is that objects that seem to be farther away are smaller, as seen as in this work by Pieter Brueghel. Objects placed higher also appear to be farther away, as seen in this work by Bartholomeus van Bassen.
One type of perspective that is closely related to linear perspective is foreshortening.
