The slider alpha controls the angle of rotation around the origin O. Change the angle of rotation and see Point A' change. You may also move Point A with the mouse.
Can you determine the coordinates of Point A' if you were given the value of the slider alpha and the coordinates of Point A? Come up with a conjecture and test it for different values of slider alpha and positions of Point A.
