How many common tangents to two circles have

WebThere are exactly two tangents to circle from a point outside the circle. We can draw only one tangent to a circle through a point that lies on the circle. A tangent cannot be drawn … WebLet there be three circles of different radii lying completely outside each other. To exclude a trivial case, assume also that their centers are not collinear, i.e. the three centers do not lie on the same straight line. Under these conditions, six external tangents to two of the three circles, taken pairwise, intersect at three points.
