 Rotations are Counterclockwise unless otherwise stated  Rotating 90° Counterclockwise or 270° clockwise  Switch x and y, then  Change sign of new x  Ex: (2,-4) rotated becomes (4,2)  Rotating 180° Counterclockwise or 180° clockwise  Change signs of x and y only  Ex: (-2,4) rotated becomes (2,-4)  Rotating 270° Counterclockwise or 90° clockwise  Switch x and y, then  Change sign of new y  Ex: (2, 4) rotated becomes (4, -2)
