Concept explainers
Billiards and mirrors. On an idealized, square billiard table, you want to hit a shot that traces a perfect diamond. To line up your shot, you take four mirrors and position them in the centers of each side wall. Before you remove the mirrors, you make your shot directly along the line from the center of one mirror to the center of the next. As you look into the facing mirror, how many billiard balls do you see?
