What describes a turn transformation in geometry?

A turn transformation in geometry is specifically defined as a rotation of a figure around a point. This means that every point of the figure moves in a circular path around a single fixed point, known as the center of rotation. The angle of rotation indicates how far the figure is turned, and the direction of rotation can be either clockwise or counterclockwise.

This transformation preserves the shape and size of the figure; it simply changes its orientation in space. The unique aspect of a rotation is that it maintains the distances between points and the overall configuration of the figure, contrasting with other transformations like reflections or translations, which do not involve this kind of rotational movement.

In summary, the correct description of a turn transformation is a rotation of a figure around a point, emphasizing the movement that characterizes this type of transformation in geometry.
