Question

Given a point on a geometric figure (1, 2) , what is the new point when the point is rotated clockwise about the origin 90 degrees?(1 point)

Answer 1

To rotate a point \((x, y)\) clockwise about the origin by 90 degrees, you can use the following transformation:

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

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

- \(x = 1\)
- \(y = 2\)

Applying the transformation gives:

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

Thus, the new point after rotating \((1, 2)\) 90 degrees clockwise about the origin is \((2, -1)\).
