Summary
DescriptionRadical axis construction.svg
English: To locate a point on the radical axis of two given circles (solid black), the dashed circle is drawn so that it intersects both given circles. The blue lines connecting their intersection points intersect at the radical center of the three circles, which lies on the radical axis of the two given circles. By repeating this with a different dashed circles, a second point on the radical axis can be constructed; the radical axis can then be drawn through the two points.
