"Rotation" means turning around a center:

The distance from the center to any point on the shape stays the same.

Every point makes a circle around the center.


You can try rotating objects (point-by-point) by any angle, around any center point here.

Try and follow what happens.

Note: If you cannot see the animation at all, you will need to install "Flash Player".
