When referring to an image or image editor, rotating 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-degrees clockwise.
As much as every tridimensional rotation has a rotation axis, also every tridimensional rotation has a plane, which is perpendicular to the rotation axis, and which is left invariant by the rotation.
Example of usage – “If the rotation axis passes internally through the body’s own center of mass, then the body is said to be autorotating or spinning, and the surface intersection of the axis can be called a pole.”
