4.3 Exploring Rotations on the Coordinate Plane

Rotations
Using the applet above, rotate the triangle 90 degrees counter clockwise (or 270 degrees clockwise). What are the coordinates of preimage point A? What are the coordinates of image point A'?
What is the "rule" for a 90 degrees CCW rotation?
Rotations
Now, use the applet above to rotate the triangle 180 degrees. What are the coordinates of preimage point A? What are the coordinates of image point A'?
What is the "rule" for a 180 degree rotation?
