The statements that require proof in a logical system are theorems and corollaries.
The statements that require proof in a logical system are theorems and corollaries.
A logical argument in which each statement is backed up by a statement that is accepted as true is a proof.
Postulates and axioms are accepted without proof in a logical system. Theorems and corollaries require proof in a logical system.

False...A postulate is a statement that does not require proof! P.S.: I know this is late, but I hope it helps!
Theorems are statements in geometry that require proof.
A Proof, 2-column proofs for geometry are common.
The answer cannot be "a proof" since that can equally be used to show that a statement must be false.
This is the composition of proof by contradiction upon logical negation.
A flow proof is a proof that uses arrows to show the flow of a logical argument.
