Question

Given a point (x,Y) what is the new point when the point is rotated counterlockwise about the orign 270 degrees

Answer 1

When a point (x, Y) is rotated counterclockwise about the origin, 270 degrees, the new coordinates of the point can be found by switching the signs of the x and Y coordinates, and then swapping their positions.

So, the new point would be (-Y, x).
