Theorem | more ... |
 A result that has been proved to be true (using facts that were already known). Example: The "Pythagoras Theorem" proved that for a right angled triangle a2 + b2 = c2 A Theorem is a major result (if it is just a minor result it is called a "Lemma") Other examples: * Intermediate Value Theorem * Binomial Theorem * Fundamental Theorem of Arithmetic * Fundamental Theorem of Algebra Lots more!
