A-theorem B-corollary C-Postulate E-Definition
We know that a postulate is a statement that is assumed to be true. So it is used to prove other geometric statements.
Also the theorems are the statement that can be considered to be true by accepted mathematical operations and arguments.
A corollary is a theorem connected by a short proof to an existing theorem.
A definition is a statement of the meaning of a term , which is absolutely used to prove statements.
