This problem is the checkpoint for determining congruent triangles. It will be referred to as Checkpoint 10.
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
Check your answers by referring to the Checkpoint 10 materials located at the back of your book.
Ideally, at this point you are comfortable working with these types of problems and can solve them correctly. If you feel that you need more confidence when solving these types of problems, then review the Checkpoint 10 materials and try the practice problems provided. From this point on, you will be expected to do problems like these correctly and with confidence.
