Constant Distance from an Interior Point to the Radical Axis

2014-03-24 08:14
This GeoGebra applet demonstrates geometric properties of the radical axis. Given a fixed circle A, a moving point C on it, and a fixed interior point D, a moving circle is drawn with center C and radius CD. It shows that the distance from D to the radical axis remains constant. This dynamic model visually reveals the invariant distance property, ideal for plane geometry.
