Given a point (x, y) on a geometric figure, what is the new point when it is rotated counterclockwise 180 degrees

If a point (x, y) on a geometric figure is rotated counterclockwise 180 degrees, the new point will be (-x, -y).

For example, if the original point is (2, 3), after rotating it counterclockwise 180 degrees, the new point will be (-2, -3).
