AAS Exploration
In the given exploration, the measures of the angles at A' and B' are fixed so that they always match the angles at A and B. In addition, segment B'C' will always be congruent to segment BC. (Note that BC would be considered a "non-included" side of angles A and B.
You are free to manipulate all the vertices of triangle ABC, and the lengths of the other sides of triangle A'B'C'. Can you find a way to make the two triangles look different from each other? Are the triangles congruent?
