Euclidean geometry Euclidean geometry Euclidean geometry is a mathematical system attributed to Alexandrian Greek mathematician Euclid, which he described in his textbook on geometry: the "Elements". Euclid's method consists in assuming a small set of intuitively appealing axioms, and deducing many other propositions (theorems) from these. Although many of Euclid's results had been stated by earlier mathematicians, Euclid was the first to show how these propositions could fit into a comprehensive deductive and logical system. The "Elements" begins with plane geometry, still taught in secondary school (High School) as the first axiomatic system and the first examples of formal proof. It goes
Ptolemy of Mauretania by an Athenian inscription, but her name has not been preserved. She may have been called Drusilla of Mauretania. His father Juba II was the son of King Juba I of Numidia, who was descended from the Berbers of North Africa and was an ally to the Roman Triumvir Pompey.
