9 Your turn Using a straight edge and either graph paper or plain paper, create a mini golf hole. Mark the flag and the ball. 2. Using your mira, find a path banking it off of 1 wall (if possible) and make your path RED. 3. Using your mira, find a path banking it off of 2 walls and make your path BLUE. 4. Using your mira, find a path banking it off of 3 or more walls and make your path GREEN. Extra Holes Another way to make a hole banking off of one wall Other practice holes 9
