which of the following require proof in a logical system? check all that apply.
a. theorems
b. corollaries
c. postulates
d. axioms

Explanation:

• Theorems are statements that must be logically proven using axioms, postulates, or already proven theorems.
• Corollaries are statements that follow directly from a proven theorem, so they require proof (often a short one based on the parent theorem).
• Postulates and axioms are foundational, self-evident statements in a logical system that are accepted without proof.

Answer:

A. Theorems
B. Corollaries
