Question

which of the following is proved by utilizing deductive reasoning? definitions undefined terms postulates theorems

Explanation:

In mathematics (especially in geometry and other deductive systems), theorems are statements that are proven to be true using deductive reasoning. Definitions are used to clarify terms, undefined terms are basic concepts without formal definitions, and postulates (or axioms) are assumed to be true without proof. So theorems are the ones proved via deductive reasoning.

Answer:

theorems
