# SSS: Exercise 3

**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 () tool and type a brief summary of the steps you took to accomplish this task. Be sure to also clearly show how you clearly know these 2 triangles are congruent. (Make sure this text is clearly visible within your applet.)*

**After doing this, save the file (call it**"

**SSS-3**")

**and make it "public".**

**Then, add this worksheet to your GeoGebra Book entitled "Congruent Triangles".**
