1. Transformations SOL 7.8

2. Vocabulary Horizontal Axis Horizontal Axis: x-axis Vertical Axis Vertical Axis: y-axis Origin Origin: intersection of the y-axis and the x- axis; point (0,0)

3. Reflection FLIP

4. Reflection Flip It may say flip or reflect the figure over the horizontal axis or x-axis!

5. Reflection Flip It may say flip or reflect the figure over the vertical axis or y-axis!

6. TransformationKeywordShortcutPicture ReflectionFlip Over x: Over y: Keep the y, change sign on x Keep the x, change sign on y

7. Rotate Turn

8. Rotate Turn It may say rotate about the origin… 90 degrees 180 degrees 270 degrees 360 degrees This was clockwise. How do you think it will change for counterclockwise?

9. TransformationKeywordShortcutPicture ReflectionFlip Over x: Keep the x, change sign on y Over y: Keep the y, change sign on x RotateTurn 90˚ CW: 90˚ CCW: 180˚: switch the coordinates and change the sign of the 2 nd new coordinate switch the coordinates and change the sign of the 1st new coordinate Change the sign on both coordinates

10. Translate SLIDE

11. Translate Slide It may say translate the figure… Right 3 Down 4 Left 2, Up 4 (4,-5) (right or left, up or down)

12. TransformationKeywordShortcutPicture ReflectionFlip Over x: Keep the x, change sign on y Over y: Keep the y, change sign on x RotateTurn 90˚ CW: switch the coordinates and change the sign of the 2 nd new coordinate 90˚ CCW: switch the coordinates and change the sign of the 1st new coordinate 180˚: Change the sign on both coordinates TranslateSlide Left (x) & down(y): - Right(x) & Up(y): + Add ordered pairs and place to be translated.

13. Dilate SHRINK GROW

14. Dilate Grow Dilate 2 (0,3) (-1,1) (1,1) (0,6) (-2,2) (2,2)

15. Dilate Shrink Dilate ½ (-4,6) (-4,4) (-2,4) (-2,3) (-2,2) (-1,2)
