Add a definition Bitangentlines can also be defined when one or both of the circles has radius zero. From Wikipedia If both circles have radius zero, then thebitangentline is the line they define, and is counted with multiplicity four. From Wikipedia Furthermore, it is included in everybitangentplane. From Wikipedia Bitangentlines can also be generalized to circles with negative or zero radius. From Wikipedia If counted with multiplicity (counting a common tangent twice) there are zero, two, or fourbitangentlines. From Wikipedia Finally, if the two circles are identical, any tangent to the circle is a common tangent and hence (external)bitangent, so there is a circle's worth of bitangents. From Wikipedia Bzout's theorem implies that a plane curve with abitangentmust have degree at least 4. From Wikipedia If one circle has radius zero, abitangentline is simply a line tangent to the circle and passing through the point, and is counted with multiplicity two.
