A 90º CCW rotation about the origin
1) Let's locate each point from the Pre-image (triangle A), to begin with:
Triangle B Triangle A
1(-2,1) (1,2)
2 (-2,6) (6,2)
3 (-5,1) (1,5)
2) Examining the given transformations:
We can state that this is a 90º CCW about the origin since
Preimage Rule Image
(x,y) (-y,x)
3) Hence, the answer is:
A 90º CCW CW rotation about the orie
