The SAS ("Side---Included Angle---Side") Triangle Congruence Theorem states that if 2 sides and their INCLUDED ANGLE of one triangle are congruent to 2 sides and their INCLUDED ANGLE of another triangle, then the two 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 "SAS-2") and make it "public".Then, add this worksheet to your GeoGebra Book entitled "Congruent Triangles".
