intersecting two times. (in response with the first answerer)
By the way, how to draw two circles which are tangent to each other?

first of all, it is not mentioned in the question that intersection should be at two points.
so, assume that intersection is only at one point.
now draw two circles with different centres and different sizes intersecting at one point . Now you can draw the tangent at the intersection point.

Just join the diameter of the 2 circles.
You will observe that diameter of the smaller and bigger circle intersect each other.
From the other end of the diameter of the smaller circle draw 2 lines joining the intersecting arc of the 2 circles.
Then you will get the required tangent.

To do it you will draw a quadrilateral as follows:
Call .A the center of one circle and .B the center of the other. Draw a segment connecting the centers of both circles(call it segment-AB). Now, using segment-AB as one leg and .A as the vertex, draw a 90-deg. angle and mark the point where it intersects the circle's edge as .C. Using .B as the vertex instead, draw a 90-deg. in the second circle and mark the point of intersection on the circle's edge as .D. The line-CD will be tangent to both circles.
