First you will investigate the Side-Side-Side (SSS) case. If
the three sides of one triangle are congruent to the three
sides of another, must the two triangles be congruent?

Construct a triangle from the three parts shown.
Be sure you match up the endpoints labeled
with the same letter. I.e A=A_{1}=A_{2.}

Compare your triangle with the triangles made by others in
your group. (One way to compare them is to place the triangles
on top of each other and see if they coincide.) Is it possible to
construct different triangles from the same three parts, or will all
the triangles be congruent?

Complete the following sentence.
If the three sides of one triangle are congruent to the three sides of
another triangle, then...
