You join the centres of the two circles. Divide this line in the ratio of the two radii. Draw the tangent from this point to either circle and extend it to touch the other circle.
A straight line touches the circumference of a circle only at one point and it is a tangent line
If the tangent circles are outside of one another, then neither passes through the center of the other. If one circle is within the other, then the inner tangent circle might contain the center point of the larger circle. There will be infinitely many inner tangent circles that do not.
No, because a tangent is the line lying on the same plane or it means there are not in the same line.
Well, since a tangent line touches a line in one spot, the Y axis could be considered tangent to the X axis.
Yes.
Yes, it can as long as it is not the tangent line of the outermost circle. If it is tangent to any of the inner circles it will always cross the outer circles at two points--so it is their secant line--whereas the tangent of the outermost circle is secant to no circle because there are no more circles beyond that last one.

If the two circles are tangent to each other,then it must be at the same point.
An external tangent is a line that is tangent to both circles but does not pass between them.
A line joining the centres of two tangent circles also passes through the point of tangency.
Tangent circles.
A tangent to a circle is a line from a point outside the circles which touches the circle at a single point.
They are the common tangents to the circles.
A common tangent is a line which is tangent to two (or more) curves.
it intersects the segment joining the centers of two circles
