Euclid (/ ˈ j uː k l ɪ d /; Ancient Greek: Εὐκλείδης; fl. 300 BC) was an ancient Greek mathematician active as a geometer and logician. [2] Considered the "father of geometry", [3] he is chiefly known for the Elements treatise, which established the foundations of geometry that largely dominated the field until the early 19th century.

Euclidean geometry is a mathematical system attributed to ancient Greek mathematician Euclid, ... the first ones having been discovered in the early 19th century.
Absolute geometry is a geometry based on an axiom system consisting of all the axioms giving Euclidean geometry except for the parallel postulate or any of its alternatives. [69] The term was introduced by János Bolyai in 1832. [70] It is sometimes referred to as neutral geometry, [71] as it is neutral with respect to the parallel postulate.
A Cartesian coordinates graph, using his invented x and y axes. One of Descartes's most enduring legacies was his development of Cartesian or analytic geometry, which uses algebra to describe geometry; the Cartesian coordinate system is named after him. He was first to assign a fundamental place for algebra in the system of knowledge, using it ...
