Question

Which of the following statements is/are correct?

1. With respect to a tangent both the circles lie on the same side, this tangent is called direct common tangent.

2. With respect to a tangent both the circles lie on the opposite side, this tangent is called transverse (indirect) common tangent.

• A. Only 1
• B. Only 2
• C. Both 1 & 2
• D. None of these

Answer 1

The correct option is C

Both 1 & 2

This is the definition of direct & transverse common tangents.

Both the statements are correct.

For eg:

In the given figure straight lines 1 & 2 are direct common tangents because both the circles lie on the same side while straight line 3 & 4 are transverse common tangents because both the circles lie on the opposite sides.
