Euclid`s Fifth Postulate
... (a) \If a straight line intersects one of two parallels (i.e, lines which do not intersect however far they are extended), it will intersect the other also." (b) \There is one and only one line that passes through any given point and is parallel to a given line." (c) \Given any gure there exists a ...

Perspective (graphical)
Perspective (from Latin: perspicere to see through) in the graphic arts is an approximate representation, on a flat surface (such as paper), of an image as it is seen by the eye. The two most characteristic features of perspective are that objects are smaller as their distance from the observer increases; and that they are subject to foreshortening, meaning that an object's dimensions along the line of sight are shorter than its dimensions across the line of sight.Italian Renaissance painters including Paolo Uccello, Piero della Francesca and Luca Pacoima studied linear perspective, wrote treatises on it, and incorporated it into their artworks, thus contributing to the mathematics of art.
