Do Now: Rotation Rules
Check off the different boxes to see how the coordinates of a triangle change when rotated by different angle measures. Note that all rotations shown in the applet below are counterclockwise.
Then, answer the questions that follow.
How do the coordinates change after a 90 degree rotation? Make sure you compare corresponding points (meaning compare A with A', B with B', and C with C')!
How do the coordinates change after a 180 degree rotation?
How do the coordinates change after a 270 degree rotation?
