Steps

  1. We have two internally tangent circles and a point A lying between them.
  2. Draw any circle e with its center at point A.
  3. Use a circle inversion to map the circles given in the problem inside circle e.
  4. Draw tangents to the new circles from the point 3.
  5. Use a circle inversion to map these tangents outside circle e.
  6. The resulting circles are the solution to the problem.
