A result that has been proved to be true (using operations and facts that were already known).

Example: The "Pythagoras Theorem" proved that a

Other examples:

• Intermediate Value Theorem

• Binomial Theorem

• Fundamental Theorem of Arithmetic

• Fundamental Theorem of Algebra

Lots more!

A Theorem is a major result (if it is just a minor result it is called a "Lemma")
