Question

Choose the required figure.

Two circles that have exactly two common tangents: Which image is it?

Answer 1

Answer is below.

Explanation:

The first image is a right triangle, circumscribed about a circle.

The second image is an obtuse triangle, circumscribed about a circle.

The third image is two circles with exactly four common tangents.

The fourth image is two circles with two common internal tangents.

The image attached, however, is two circles that have exactly two common tangents; they are overlapping.

Hope it helps.

Answer 2

not sure how the first two pictures apply here, since they're just a single circle.

check the picture below.

the one on the left can have 3 common tangent lines, the one on the right, only two common ones.
