Answer 1

well the 2 circles, one needs to be inside another, and the have a common point of contact.

the tangent then passes through the point of contact.

looking at the diagram, T is the point of contact.

so you want 2 circles on the same side of the tangent, and 1 circle inside the other.

hope it helps.

I'm sorry, that still isn't making sense. Thanks for the help though.
