same as the first one but use classifier C instead of a closed 5 to symbolize an object. And the index finger is separated from the object to represent the more general case.
To rotate an object in a transformation means to pick a point and spin the object a certain number of degrees around the point and redrawing the object.
You can rotate an object around a point inside or outside the object itself. A tire rotates around the axle at its center. The letter G in "Goodyear" on the tire doesn't rotate around the center of the G but 15 inches away at the center of the tire.
