Existence of Isometries
Compose transformations to create an isometry mapping triangle ABC to triangle DEF. Then do the same to map triangle ABC to triangle GHI.
Additional Challenge: The proof of the Existence of Isometries Theorem proves that you can use 2 or 3 reflections. Try to find a single rotation that maps triangle ABC to triangle DEF. Find a single glide reflection that maps triangle ABC to triangle DEF.
