How many quadrants does a 270-degree rotation move a shape?

A 270-degree rotation moves a shape three quadrants because the coordinate plane is divided into four quadrants, each representing a 90-degree section. When you rotate a shape 90 degrees, it moves to the next quadrant, and continuing this for an additional 180 degrees covers two quadrants. Therefore, a 270-degree rotation can be understood as a 90-degree rotation plus an additional 180 degrees, which effectively turns the shape through three quadrants in total. This means that after rotating a shape 270 degrees, it will end up in the position of the shape that was originally in the opposite direction of where it started, confirming that the answer is indeed three quadrants.
