Sure. They would have one of two appearances. Either they look like a figure ' 8 '
with a line across the middle, or else they look like two soap bubbles, one inside
the other, hanging from the line.

If the two circles are tangent to each other,then it must be at the same point.
No, tangent circles do not have the same center. They just touch at the side. Here is an example:
Yes a tangent is a straight line thattouches a curve at only one point But there is a tangent ratio used in trigonometry
A tangent line is a line that is parallel to and intersecting a point on a curve, where the limit of the distance between two points on that curve (one of them being the point in question) and those two points also being on that line approaches zero. Since a straight line has only one slope, at all points on the line, then there can only be one tangent line to a straight line, and the tangent line is the same line as the straight line.
To measure the point at which two tangents intersect each other, find an equation for each tangent line and compute the intersection. The tangent is the slope of a curve at a point. Knowing that slope and the coordinates of that point, you can determine the equation of the tangent line using one of the forms of a line such as point-slope, point-point, point-intercept, etc. Do the same for the other tangent. Solve the two equations as a system of two equations in two unknowns and you will have the point of intersection.
