Question

What is the difference between a postulate and theorem in Geometry?

Answer 1

I believe a theorem can be proven, while a postulate is merely affirmed.

Answer 2

Hmmmm... I think its the other way around right ?

Answer 3

A postulate is an assumption. We assume a certain fact to be true because it makes sense to us. A theorem is a statement that is proven from the postulates.

Answer 4

Another word you may hear for "postulate" is "axiom." Both are often used interchangeably.
