Question

which of the following types of statement cannot be used to explain the steps of a proof? check all that apply. guess theorem conjecture postulate

Explanation:

A proof requires established facts. A guess is an unsubstantiated idea, and a conjecture is an unproven statement. In contrast, a theorem (a proven statement) and a postulate (an accepted - without - proof statement) can be used in proofs.

Answer:

A. Guess, C. Conjecture
