Yes, it is true. However, it is possible that the postulate is false. For example, although in plane geometry Euclid's parallel postulate is true, it is not true for alternative geometries.
Theorem
False. Definitions do not need to be proven.
If they are known not to be true then they are no longer postulates but discarded theories.
True. Axioms and postulates do not require proof to be used.
what are the postulates of the theroy
No. Postulates are the foundations of geometry. If you said they were wrong then it would be saying that Euclidean geometry is wrong. It is like if you asked how do we know that English is right. It is how the English language works. So no postulates do not need to be proven.

Theorem
Every statement apart from the axioms or postulates.
A therom in math is a law that has been proven by using other theroms or postulates. They are commonly found in Geometry and above.
A postulate is assumed to be true while a theorem is proven to be true. The truth of a theorem will be based on postulates.
No. A postulate need not be true.
False. Definitions do not need to be proven.
Postulates were first used by the Early Greeks.
Postulates are statements that are assumed to be true without proof. Theorums are statements that can be deduced and proved from definitions, postulates, and previously proved theorums.
They are a set of conditions which need to be fullfilled to prove that a specific organism causes a specific disease.
I do not believe there are any postulates: they can be proved and therefore are not postulates.
