SSS: Exercise 1

The SSS ("Side-Side-Side") Triangle Congruence Theorem states that if 3 sides of one triangle are congruent to three sides of another triangle, then both triangles are congruent. In the applet below, use the transformational geometry tools of GeoGebra to show that triangle ABC is congruent to triangle DEF. Once you have done so, click the text (Toolbar Image) tool and type a brief summary of the steps you took to accomplish this task. Then explain completely and precisely how you know that the two triangles are congruent. After doing this, save the file (call it "SSS-1") and make it "public".
