Foundations of geometry association of meanings makes the axioms of the system true statements, then the interpretation is called a model of the system. In a model, all the theorems of the system are automatically true statements. In discussing axiomatic systems several properties are often focused on: "Euclidean geometry" is a mathematical system attributed to the Alexandrian Greek mathematician Euclid, which he described (although non-rigorously by modern standards) 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
Antiochus (father of Seleucus I Nicator) Antiochus (father of Seleucus I Nicator) Antiochus (Greek: Ἀντίοχος; fl. 4th century BC) was a Macedonian man who lived during the time of Philip II of Macedon (ruled 359-336 BC).
