Illustrate a geometric diagram which includes an origin, a distinctly identifiable point placed at coordinates (1, 2), and the same figure rotated 180 degrees clockwise about the origin. The focus of the image is to demonstrate the movement of the point after rotation, without the inclusion of any textual elements.

Given a point (1, 2) on a geometric figure, what is the new point when the figure is rotated clockwise about the origin 180 degrees?

When a point is rotated clockwise about the origin 180 degrees, the x-coordinate of the point is negated, and the y-coordinate of the point is negated.

So, the new point when (1, 2) is rotated clockwise 180 degrees about the origin is (-1, -2).
