VISUAL THINKING
In miniature golf, a player tries to hit a ball into a hole in as few
strokes as possible. Obstacles on the course, such as water, often
get in the way and you have to bank your shot off a rail in order to
get the ball rolling toward the hole. Below is a three-hole miniature
golf course showing the angles a player would take. Use your
protractor to answer 1–3.
