10-109.

This problem is the checkpoint for determining congruent triangles. It will be referred to as Checkpoint 10. Homework Help ✎

Determine if the left triangle is congruent to the right triangle. If they are congruent, state the congruence condition you used, state a sequence of rigid transformations that maps the left triangle onto the right, and write a triangle congruence statement like $∆ABC ≅ ∆DEF$. If they are not congruent, state why not.
