A rotation is when you turn a shape using a specific angle measurement and direction around a certain point. The angle measurement used is the angle of rotation. We will be working with specific degrees of rotation, which we should have an understanding of what these look like from the previous unit on angles. The point that the shape is being rotated around is the point of rotation, and the direction (clockwise or counterclockwise) is the direction of rotation.
We have noted some real life examples of rotations and their centers of rotation during class.
Notice in the example below that the center of rotation that is used is also a point on the shape. This can be the case, or the shape may be rotated around the origin.
