Circles with Internal Tangency, Third Passes Through the Point of Tangency
Number of solutions: 2
GeoGebra construction
Steps
- We choose the reference circle for the inversion. Its center is chosen at the intersection point of all three circles.
- We apply the circular inversion to the given circles. Since all of them pass through the center of the reference circle, they are transformed into lines.
- We find circles tangent to the images of the given circles. Their centers are found using angle bisectors.
- We invert the found circles back using the same inversion.
- The problem has two solutions.
