2D. Explanation of Invariance of the sum of squares of distances by using the Steiner theorem.

This applet is a generalization of an earlier [url=https://www.geogebra.org/m/m8fdnkdz]applet[/url].[br] The sum of the squares of the distances from any selected [b][color=#ff7700]point[/color][/b] to the [color=#0000ff]points [/color]of some point system is conserved when that selected point is on some circle whose center is at the [color=#ff00ff]center of mass[/color] of the point system. Result independent of number of points in system.
