The 90-degree clockwise rotation represents the movement of a point or a figure with respect to the origin, (0, 0). If I didn't have it, I would probably be failing math. If an original point, anywhere in the x-y plane is rotated 180 degrees. The mathematics behind this behavior is called orientation. Topic: Rotation. Anticlockwise involves a turn to the left, against the direction of a clocks hands. Water from a water trough that is positioned above the water wheel is poured into the paddles of the water wheel to force it to rotate in a clockwise direction. 90 degrees counter-clockwise from quad I would turn any point from (+,+) to a point which is (-,+). The graph of the four rotated points is shown in the coordinate plane below. Another great example of rotation in real life is a Ferris Wheel where the center hub is the center of rotation.
