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 180 degrees clockwise about the origin, the new coordinates are given by (-x, -y) where the original coordinates are (x, y).

So, for the point (1, 2), the new point after rotating 180 degrees clockwise about the origin is (-1, -2).
