1. Lesson 5-6 Transformations
Obj: I can transform plane figures using translations, rotations and reflections HWK: p all Vocab: 1) transformation 2) image 3) translation 4) reflection 5) rotation 6) center of rotation

2. Ex 1) Graph the translation of ΔABC 3 units left and 4 units up

3. Ex 2) Graph the translation of ΔABC 2 units right and 3 units down

4. Ex 3) a) What are the coordinates of ΔABC in Ex 1 before and after the translation? Write a rule to get from A to A΄

5. Ex 3) b) What are the coordinates of ΔABC on Ex 2 before and after the translation? Write a rule to get from A to A΄

6. Ex 3) c) What do you notice about the rule you came up with and the way that you translated each figure?

7. Ex 4) Graph the reflection of ΔABC across the y-axis

8. Ex 5) Graph the reflection of quadrilateral ABCD across the y-axis

9. Ex 6) Graph the reflection of quadrilateral ABCD across the x-axis
D C

10. Ex 7) a) What are the coordinates of ΔABC in Ex 4 before and after the reflection? Write a rule to get from A to A΄.

11. Ex 7) b) What are the coordinates of quad ABCD in Ex 5 before and after the reflection? Write a rule to get from A to A΄.

12. Ex 7) c) What are the coordinates of quad ABCD in Ex 6 before and after the reflection? Write a rule to get from A to A΄.

13. Ex 7) d) What do you notice about the rule you came up with and the way that you reflected each figure?

14. Ex 8) Graph the rotation of ΔABC of 90°, 180°, and 270° around the origin
C B

15. Ex 9) Graph the rotation of ΔABC of 90°, 180°, and 270° around the origin
C B

16. Ex 10) a) What are the coordinates of ΔABC in Ex 9 before and after the rotations? Write a rule.

17. Ex 10) b) What do you notice about the rule you came up with and the way the figure is rotated?
