Compare and contrast postulate and a conjecture

Postulate - this is also called as axiom. This study is accepted without asking for any proof. This is considered as true without further proof. IT is simply considered as self-evident. It is usually agreed by anyone to be true and acceptable.

Example of postulate is to prove a simple triangle as congruent.

While conjecture - considered as proposition in which it needs to provide value proof or evident in order for it to be considered as true.

Examples of conjecture are four color theorems and Fermat’s Last theorem.
