Rotating a figure means turning the figure around a point. The point can be on the figure or it can be some other point. The shape still has the same size, area, angles and line lengths. reflection: It is also called a flip. When a figure is flipped over a line. Each point in a reflection image is the same distance from the line as the corresponding point in the original shape. The shape still has the same size, area, angles and line lengths.
