A rotation (or turn) is a transformation that turns a line or a shape around a fixed point. This point is called the center of rotation. We usually measure the number of degrees of rotation of a shape in a counterclockwise direction.

Math Rotations
Students learn that when a figure is turned to a new position, the transformation is called a rotation.
Estimate the number of degrees and state the direction in which the following figure has been rotated.
