Non-Example: AA

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 B onto E.
Now, identify and perform the transformation the maps Segment C'B' onto Segment EF. (Hint: The measure of Angle C'B'F is 80 degrees.)
Notice that Point C' and F do not coincide. Why not?
Lastly, perform the transformation that maps Angle B onto Angle E. Notice that the triangles are not congruent.
