Three Intersecting Circles
Number of solutions: 8
GeoGebra construction
Steps
- Construct three hyperbolas whose foccuses are at the centres of the circles and which pass through their intersection.
- Construct two ellipses whose foccuses are at the centers of the given circles and which pass through their intersection (can be done with any circle from the given set).
- Two intersections of three hyperbolas are two solutions, different intersections of hyperbolas and ellipses hide 6 more solutions.
- We havae 8 solutions
