Transformations
SOL 8.8
Students will be using the
8.8 Transformation Chart for Notes
Vocabulary
Horizontal Axis: x-axis
Vertical Axis: y-axis
Origin: intersection of the y-axis and the x-axis; point (0,0)
Reflection
Reflection Flip
It may say flip or reflect the figure over the horizontal axis or x-axis!
Reflection Flip
It may say flip or reflect the figure over the vertical axis or y-axis!

Reflection FlipOver x:
Over y: Keep the y, change sign on x
Keep the x, change sign on y
Rotate
Rotate TurnIt may say
rotate about the origin…90 degrees
180 degrees
270 degrees
360 degreesThis was clockwise. How
do you think it will change for
counterclockwise?

Reflection FlipOver x: Keep the x, change sign on y
Over y: Keep the y, change sign on x
Rotate Turn
90˚ CW:𝐶.𝑐𝑙𝑜𝑐𝑘𝑤𝑖𝑠𝑒 𝐶𝑙𝑜𝑐𝑘𝑤𝑖𝑑𝑒
90˚ CCW:
180˚:
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
Translate
Translate Slide
It may say translate the figure…
