If two circles intersect at two points, how many common tangents are possible if the circles have the same radius?
Show answer & explanation
Correct answer: B
Explanation
Two circles intersect at two points.
Both circles have the same radius.
If two circles intersect at two points, then two common tangents are possible between them (two external tangents).
When two circles intersect, no internal tangents are formed, only external tangents are formed.
