1. One straight line r is tangent to
a circumference when they have a single
point of contact M and the straight line
is perpendicular to the its radius at M.
2. Two circumferences are tangent
when the straight line joining their
vertices passes through their point
of tangency M.
3. A circumference is tangent to two
convergent lines when its center is
on their angle bisector and has one
point of tangency with each line.
