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.
