In the given figure we can observe a triangle with vertices located at:
(-3,-2)
(-5,-4)
(1,-5).
We need to draw it after a 90° clockwise rotation.
We can apply the rule for 90° clockwise rotation, which is:
Each point of the given figure has to be changed from (x, y) to (y, -x) and then we need to graph the new coordinates.
By applying the rule to the given coordinates we obtain:

Now we have to draw the new coordinates:
