Use Identity Property Starter File to respond to the questions below.
Scale
1 With your partner, predict what belongs in each blank below. Then, test your prediction using Pyret to see if you were correct.
Scaling by 1 will produce an image that is
Scaling by 1 /2 will produce an image that is .
Scaling by 1 /10 will produce an image that is .
Scaling by 0 will produce
2 Place a checkmark next to lines of code that you predict will produce an image identical to the original. Then, run the code to test your predictions.

5 What did you discover? For what degrees did rotate produce an identical image?
Flip
6 In the Interactions Area (right), try out flip-vertical(dog), then try flip-horizontal(dog). How is the image returned different from the original?
7 Place a checkmark next to lines of code that you predict will produce an image identical to the original. Then, run the code to test your predictions.
