2. Rotation – A circular movement around a fixed point Rotation

3. 270 degree rotation (counter clockwise) 180 degree rotation 90 degree rotation (counter clockwise)

4. A positive number of degrees indicates a counter clockwise rotation 5 -5 5 A B C Rule: (x,y) (-y,x) A’ B’ C’ A (4, 3) B (1, 3) C (1, 1) C’ (-1, 1) B’ (-3, 1) A’ (-3,4)

5. A positive number of degrees indicates a counter clockwise rotation 5 -5 5 A B C Rule: (x,y) (-x,-y) A’ B’ C’ A (4, 3) B (1, 3) C (1, 1) C’ (-1,-1) B’ (-1,-3) A’ (-4,-3)

6. A positive number of degrees indicates a counter clockwise rotation 5 -5 5 A B C Rule: (x,y) (y,-x) A’ B’ C’ A (4, 3) B (1, 3) C (1, 1) C’ (1,-1) B’ (3,-1) A’ (3,-4)

7. A 90 degree counterclockwise turn…… 5 -5 5 A B C …..is the same as a 270 degree clockwise turn! A’ B’ C’

8. 5 -5 5 A B C A’ B’ C’ A 270 degree counterclockwise turn…… …..is the same as a 90 degree clockwise turn!

9. 5 -5 5 A B C A’ B’ C’ Rotate 90 degrees about the origin Remember the Rule: (x,y) (-y,x) A (-2, 4) B (-4, 2) C (-2, 0) A’ (-4, -2) B’ (-2, -4) C’ (0, -2)

10. 5 -5 5 A B C A’ B’ C’ Rotate 180 degrees about the origin Remember the Rule: (x,y) (-x,-y) A (-1, 5) B (-4, 2) C (0, 1) A’ (1, -5) B’ (4, -2) C’ (0, -1)

11. 5 -5 5 A B C A’ B’ C’ Rotate 270 degrees about the origin Remember the Rule: (x,y) (y,-x) A (1, 4) B (-2, 3) C (2, 1) A’ (4, -1) B’ (3, 2) C’ (1 -2)
