Mapping Congruent Figures using only Reflection
Three Reflections Conjecture:
Seeing is Believing
Precisely describe the general technique you used to map the figures onto each other using only reflection. Discuss how your results support or refute the Three Reflections Conjecture.
Explain how you were able to establish that poly1 was congruent to poly4 according to the transformation definition of congruence. Explain why you were able to accomplish this using only translations and rotations (i.e., without using reflections).
Write a short paragraph proof to explain how establishing poly1 congruent to poly4 allows you to conclude that poly1 is congruent to poly2.
