Question

Describe how to find the coordinates of the image of a point after a 270° rotation.

Answer 1

When any point say (x,y) is rotated 270 degree counterclockwise then it changes to (y,-x).

So for any image, you can collect given coordinate points

then apply above formula like if given point is (1,3) then it will change to (3,-1) after 270 degree counterclockwise rotation.
