Given a point (1, 2)

Question

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

Answer 1

To rotate a point \((x, y)\) clockwise 180 degrees about the origin, we can use the following transformation:

\[ (x, y) \rightarrow (-x, -y) \]

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

\[ (1, 2) \rightarrow (-1, -2) \]

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