Consider two non-intersecting, non-congruent circles. What is the locus
of centers of circles which are tangent to each of these two circles?

ANSWER:

Draw a line between the centers of the given circles. Consider the
segment from the end of one circle to the end of the other. The locus
is the line perpendular to the line between the centers at the midpoint of
the segment.

There must be a better way of explaining this!
