Question

How many common tangents can be drawn for two disjoint circles?

• A. 2
• B. 3
• C. 4
• D. 1

Answer 1

The correct option is C 4

$\Rightarrow$ There can be four common tangents to two circles. The tangents can be either direct or transverse.

$\Rightarrow$ When the two circles neither intersect nor touch each other, there are four common tangents.

$\Rightarrow$ But when they intersect there are two common tangents, both of then being direct.
