90 and 270 degree rotations quick check

To perform a 90-degree rotation on a point or shape, you can switch the x and y-coordinates, making the new x-coordinate the negative value of the original y-coordinate, and the new y-coordinate the positive value of the original x-coordinate. For example, a point (2,3) would become (-3,2) after a 90-degree rotation.

To perform a 270-degree rotation, you can use the same logic as a 90-degree rotation but with the signs switched. The new x-coordinate would be the positive value of the original y-coordinate, and the new y-coordinate would be the negative value of the original x-coordinate. Using the same example, (2,3) would become (3,-2) after a 270-degree rotation.
