Rotate
When referring to an image or image editor, rotate is a feature that allows you to turn an image in a clockwise or counterclockwise direction. For example, many editors allow you to rotate images 90, 180, or 270. Below is an example of the Computer Hope logo and what it would look like rotated at 90, 180, and 270 clockwise.
