How do postulates differ from theorems?

Postulates are fundamental assumptions or statements accepted as true without proof, serving as the foundational building blocks for a mathematical system. Theorems, on the other hand, are propositions that have been proven to be true based on postulates and previously established theorems. While postulates provide the groundwork for reasoning, theorems require a logical proof to establish their validity. In essence, postulates are accepted truths, whereas theorems are derived truths.
