This rotations exploration is like the one we looked at in class today. Feel free to play with it. Remember that you can change the angle using the slider, you can move the center of rotation G and you can move the pre-image polygon (ABCDE) or any point on the polygon.
Remember that the distance from the center of rotation to a point on the pre-image (object) is the same as the distance from the center of rotation to the corresponding point on the image (rotated object). These are shown by the circles. Remember that positive angle rotations are counter-clockwise, while negative angle rotations are clockwise.
