Question

1. an informal proof uses ______________ to show that a conjecture is true.

algebra rules
geometry rules
specific examples
theorems

Explanation:

An informal proof is a proof that is written in paragraphs and uses words to explain why a conjecture for a given situation is true. It often uses specific examples to illustrate the truth of the conjecture. Algebra rules and geometry rules are more formal and are used in formal proofs. Theorems are statements that have been proven, and while they can be used in proofs, an informal proof typically relies on specific examples rather than just citing theorems.

Answer:

specific examples
