Given a point (x, y) on a geometric figure, what is the new point when the figure is rotated counterclockwise about the origin 180 degrees?
To find the new point when a figure is rotated counterclockwise about the origin 180 degrees, we need to apply the following transformation:
(x', y') = (-x, -y)
Where (x, y) is the original point and (x', y') is the new point after rotation.
For example, if the original point is (2, 3), applying the transformation we get:
(x', y') = (-2, -3)
So, the new point after rotating the figure counterclockwise about the origin 180 degrees from (2, 3) is (-2, -3).
