Final answer:
A postulate is not another name for a conjecture we believe to be true. A postulate is a statement that is assumed to be true without proof, while a conjecture is a statement that is believed to be true but has not been proven.
Step-by-step explanation:
No, a postulate is not another name for a conjecture we believe to be true. A postulate, also known as an axiom, is a statement that is assumed to be true without proof, and is used as a starting point for reasoning in mathematics. On the other hand, a conjecture is a statement that is believed to be true but has not been proven yet. Conjectures are often based on patterns and observations, but they require rigorous mathematical proof to be established as true.
