Euclidian Geometry is the study of geometry based on definitions, undefined terms (point, line and plane) and the assumptions of the mathematician Euclid (330 BC)

Euclid's text Elements was the first systematic discussion of geometry.  While many of Euclid's findings had been previously stated by earlier Greek mathematicians, Euclid is credited with developing the first comprehensive deductive system.  Euclid's approach to geometry consisted of proving all theorems from a finite number of postulates (axioms).
