Steps

  1. Draw a circle centered at point A and proceed with a circle inversion.
  2. Invert all objects in the problem through the circle inversion from step 1. This leaves point A at infinity.
  3. Draw the common tangents of the circles. They meet the point at infinity.
  4. We invert the tangents from step 3 through circle inversion from step 1.
  5. 4 solutions arise.
