Question

The point (2,1) is rotated 90 degrees clockwise using center (0,0). What are the coodinates of the image?

Answer 1

(1,-2)

Explanation:

Rotation of Figures

When we rotate a figure 90 degrees clockwise across the origin, each point of the given figure has to be changed from (x, y) to (y, -x).

We are given the point (2,1) and it is rotated 90 degrees clockwise across the origin, thus the image has coordinates (1,-2).

The figure below shows the point and its image.
