The goal of this activity is to determine if we can conclude that two triangles are congruent with only some information about their sides and angles.

What information about the triangles is given?

Identify and perform the transformation that maps A onto D.

Identify and perform the transformation that maps B onto E. How do you know the points coincide? (Hint: Angle B'A'E measures 60 degrees)

Lastly, perform the transformation that maps Segment A'C' onto Segment DF. Why do C and F NOT coincide?
