Answer
66.5° N and 66.5° S
Explanation
The Arctic and Antarctic Circles lie at approximately 66.5° north and south latitude, which is 23.5° from their respective poles and equivalently 23.5° beyond the equator toward the poles. **Key takeaway:** Polar circles are near 66.5° latitude, or 23.5° from the poles. **Glossary:** **Arctic Circle**: The northern polar circle; **Antarctic Circle**: The southern polar circle.
