# 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.*

*After doing this, save the file (call it "SSS-1") and make it "public".*

**Once you have done so, click the text () 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.**## New Resources
