The word 'congruent' conveys what kind of relationship?

• A. unrelated
• B. varying widely
• C. agreement or compatibility; corresponding
• D. contradictory

Answer: (C)

Congruence describes a matching relationship where two things fit together exactly. In geometry, that means they have the same shape and size, so you can place one over the other perfectly; their corresponding sides and angles match precisely. Outside of geometry, congruent is used to express agreement or compatibility—two ideas, beliefs, or pieces of information that line up and correspond with each other.

This is why the best choice captures agreement or compatibility, or the idea of corresponding parts. The other options describe no relation (unrelated), major differences (varying widely), or opposition (contradictory), which run counter to what congruent communicates.
