The SSS Triangle Congruence

To construct a triangle congruent to triangle ABC, move the slider to the right. To see the construction steps, move the slider slowly to the extreme right. This is a Java Applet created using GeoGebra from www.geogebra.org - it looks like you don't have Java installed, please go to www.java.com

When n = 16, move the vertices of triangle ABC. What do you observe? 

The applet above shows that if the three corresponding sides of two triangles are congruent, then the two triangles are congruent.
