  6. 9-2 Translations • Example: Translate rectangle PQRS 5 units to the right and 4 units down P(-3, 5) Q(-4, 2) R(3, 0) S(4, 3)

  7. 9-2 Translations • Translations by repeated reflections: • Perform a reflection in one line. • Reflect the image in a 2nd║ line. • Result is a translation of the original preimage. • “Composition of Reflections”.
