What would be your guess and why?

anonymous · Answer

I think it's B but I only think that since I know it can't be postulates lol

anonymous · Answer

Why can't a postulate be used to prove a theorem?

anonymous · Answer

cause postulates are just assumptions and theorems require facts

anonymous · Answer

Hmm.. well, some postulates are facts.

You might be thinking of how theories are used to explain and interpret facts. If you're talking about mathematical theorems, though. You need a starting point. It is impossible to make a deduction without some starting assumptions.

anonymous · Answer

A postulate is merely a statement that is accepted as true without proof. This may be because it is an axiom and is self-evidently true and cannot be proved, or the postulate might be a previously proved theorem and does not require proof (again.)

And, of course, definitions are needed because you have to sound like you know what you're talking about. ..
