on a geometric figure, what is the new point when the figure is rotated clockwise about the origin 180 degrees?

1 answer

Rotating a point \((x, y)\) 180 degrees clockwise about the origin results in moving the point to \((-x, -y)\).

Given the point \((1, 2)\):

  1. The new x-coordinate is \(-1\) (which is \(-1\) times the original x-coordinate).
  2. The new y-coordinate is \(-2\) (which is \(-1\) times the original y-coordinate).

So, after rotating the point \((1, 2)\) 180 degrees clockwise about the origin, the new point will be:

\[ (-1, -2) \]
