  1. Transformations SOL 8.8

  2. Vocabulary Horizontal Axis: x-axis Vertical Axis: y-axis 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. Transformations Chart Keep the x, change sign on y Keep the y, change sign on x

  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. Transformations Chart switch the coordinates and change the sign of the 2nd new coordinate switch the coordinates and change the sign of the 1st new coordinate Change the sign on both coordinates

  10. Translate SLIDE

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

  12. Transformations Chart 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)

  16. Transformations Chart Multiply

  17. Let’s Try Some! Next, there will be some examples. These examples are just asking you too identify the transformation on appearance only.
