Question

coplanar points are points that lie on the same plane. a. undefined terms b. defined terms c. postulates d. theorems

Explanation:

A defined term is one that has a formal definition. Since "coplanar points" is given a clear - cut definition (points that lie on the same plane), it is a defined term. Undefined terms are basic building - blocks like point, line, and plane with no formal definition. Postulates are statements assumed to be true without proof, and theorems are statements proved from postulates and other theorems. This is simply a defined term.

Answer:

B. Defined Terms
