- AThey touch internally
- BThey touch externally
- CThey are concentric
- DThey do not touch
Step-by-Step Solution
Exactly 3 common tangents occur only when two circles touch externally (2 direct + 1 at point of contact).
Answer: B) They touch externally
Two circles touch each other. A student counts the common tangents and finds exactly 3.
From this count alone, what can be concluded about how the circles touch?
