Question

Choose a rule to describe the counter-clockwise rotation given the black pre-image and the blueimage:Time ElAttempt a3 MinutALOr (360.0180.0Or 190.00270.0

Answer 1

First, let's locate the coordinate of N in the preimage

N (-1 , 2)

Next, locate the coordinate of N' in the image

N' (-2, -1 )

This shows that

(x , y ) ⇒ (-y , x)

Hence, the rule applied is 90 degree anti clockwise rotation
