Help me. Look at the inner and outer rims of the circular plate shown below. What are they called? A. Concentric chords B. Concentric circles C. Concentric radius D. Concentric secants I thought it was A, but I got it wrong.

OpenStudy (anonymous):

No, B. They are circles and "concentric" mean "Same center".
