For two circles, there are generally four distinct lines that are tangent to both (bitangent) – if the two circles are outside each other – but in degenerate cases there may be any number between zero and four bitangent lines; these are addressed below. For two of these, the external tangent lines, the circles fall on the same side of the line; for the two others, the internal tangent lines, the circl… WebLength of Transverse Common Tangent. Example : Find the number of common tangents to the circles x 2 + y 2 = 1 and x 2 + y 2 – 2 x – 6 y + 6 = 0. Solution : Let C 1 be the center of circle x 2 + y 2 = 1 i.e. C 1 = (0, 0) And C 2 be the center of circle x 2 + y 2 – 2 x – 6 y + 6 = 0 i.e. C 2 = (1, 3) Let r 1 be the radius of first circle ...
