Question
Do the two circles with centers A and B and radii R and r intersect each other?
Statement (I): AB > R - r
Statement (II): AB > R + r
- If the question can be answered with statement I alone but not statement II alone, or can be answered with statement II alone but not statement I alone
- If the question cannot be answered with statement I alone or with statement II alone, but can be answered if both statements are used together
- If the question can be answered with either statement alone
- If the question cannot be answered with the information provided
Explanatory Answer
Statement (I): AB > R - r
Not enough. May intersect, may be “parallel” or "disjoint".
Statement (II): AB > R + r
SUFFICIENT. Circles cant intersect. Have to be separate.
