This is the key difference between postulate and theorem. Theorems are often based on postulates. A postulate is a statement that is assumed to be true without any proof. Postulates are also known as axioms. Postulates do not have to be proven since they are visibly correct. For example, the statement that two points make a line is a postulate. Postulates are the basis from which theorems and lemmas are created.
A theorem can be derived from one or more postulates. Add a comment. Active Oldest Votes. Any line segment can be extended to an infinite line. Given a point and a radius, there is a circle with center in that point and that radius.
All right angles are equal to one another. If a straight line falling on two straight lines makes the interior angles on the same side less than two right angles, the two straight lines, if produced indefinitely, meet on that side on which are the angles less than the two right angles.

Clear and informal, while still accurate. Better than wikipedia's, in my opinion. I don't think it would be obvious to anybody except to extraordinary geniuses like Euler, Gauss or Ramanujan.. Show 1 more comment. What is the difference between Axioms and Postulates?
This isn't a bad explanation, and thanks for attempting to explain the difference, but I'm still a bit fuzzy on the historical distinction as used by Aristotle and Euclid. It is not the way the words "axiom" and "postulate" are being used in math and logic. For example, the axioms of a ring include left and right distributivity of multiplication over addition; the axioms of a commutative ring include commutativity of multiplication; but suddenly that means that we must arbitrarily pick only left or right distributivity as an axiom.

Caicedo is correct that this distinction doesn't form a part of modern mathematical practice, that doesn't make it wholly valueless. The net collection of definitions, propositions, theorems, form a mathematical theory.

The truth is that a concept or thought is a distinct entity from a symbolic representation, and when a concept is grasped directly, total understanding is possible in spite of the apparent circularity of defining words using other words.
