Open Ended

How many degrees was the image rotated?

Type response here

What is the rule for a 90 degree rotation?

How would you answer this?

Prove that you’ve identified the correct rule by finding the pre-image coordinates for A and then applying the rule to end with the image’s coordinates for A’.

Multiple Choice

How many degrees was the image rotated?

180

270

360
