To rotate a point 90° clockwise about the origin, you can use the following transformation:
If the original coordinates are (x, y), the new coordinates after a 90° clockwise rotation will be (y, -x).
For point B (2, 4):
– x = 2
– y = 4
Applying the transformation:
– New x = 4
– New y = -2
So the new coordinates of point B after the rotation will be (4, -2).
