1. Problem Description
The problem asks us to determine if the circles in the figure are congruent, concentric, or neither. The figure contains what appear to be US coins. Congruent circles have the same radius. Concentric circles have the same center.
2. Solution Steps
First, observe the coins in the image. From left to right, the coins appear to be a quarter, a nickel, a penny, and a dime.
A quarter, a nickel, a penny, and a dime have different diameters (and therefore different radii).
Therefore, the circles are not congruent.
The circles do not share the same center, so the circles are not concentric.
Therefore, the answer must be neither.
3. Final Answer
Neither.
