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?


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
