Two Circles With Inner Contact, Point Between The Circles
Number of solutions: 3
GeoGebra construction
Steps
- We have two internally tangent circles and a point A lying between them.
- Draw any circle e with its center at point A.
- Use a circle inversion to map the circles given in the problem inside circle e.
- Draw tangents to the new circles from the point 3.
- Use a circle inversion to map these tangents outside circle e.
- The resulting circles are the solution to the problem.
