A Circle Tangent Medley
Author: Jon Choate
One of the classic problems
in ancient geometry
is: given three circles A, B,
and C that are pairwise tangent,
find two more circles each tangent
to circles A, B, and C. These two
circles came to be known as
Soddy Circles. This problem
sounded to me like a great one to
solve using GeoGebra or any
other construction package and a
computer algebra system. What
follows is a solution.
