Final answer:
The legal doctrine requiring acceptance to match the offer's terms in contract law is known as the mirror image rule.
Step-by-step explanation:
The legal doctrine that states an acceptance must be on precisely the same terms as the offer is known as the mirror image rule.
This rule is a principle in contract law that requires for an acceptance to be legally binding, it must exactly match the offer made, without any modifications. If the acceptance does not mirror the offer, it is not valid; instead, it may constitute a counteroffer.
The mirror image rule is significant because it aims to ensure that the parties involved in the contract are in full agreement on the terms, and it helps prevent disputes about what the parties actually agreed upon.
The classic application of this rule can be seen in situations where contractual rights are being established, and the law requires clarity to enforce these rights and provide legal recourse.
