|axiom (āk'sē-əm) Pronunciation Key
A principle that is accepted as true without proof. The statement "For every two points P and Q there is a unique line that contains both P and Q" is an axiom because no other information is given about points or lines, and therefore it cannot be proven. Also called postulate.
In mathematics, a statement that is unproved but accepted as a basis for other statements, usually because it seems so obvious.
Note: The term axiomatic is used generally to refer to a statement so obvious that it needs no proof.
