Transformation Reflection Keyword Flip Shortcut Over x: Keep the x, change sign on y Over y: Keep the y, change sign on x Picture

Rotate T n r u

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?

Transformation Reflection Keyword Flip Shortcut Over x: Keep the x, change sign on y Over y: Keep the y, change sign on x 90˚ CW: switch the coordinates and change the Rotate Turn sign of the 2 nd new coordinate 90˚ CCW: switch the coordinates and change the sign of the 1 st new coordinate 180˚: Change the sign on both coordinates Picture
