In American billiards, you need to bounce your cue ball off two cushions before hitting another ball. How long is the path taken by the cue ball, A? We can create the correct path in Geometry Expressions by reflecting the target ball B in the two cushions (IJ and JG), drawing a line between the cue ball and the twice-reflected target B", then reflecting this line back. The path length is the same as the distance between the cue ball and the twice-reflected target.
Note: The downloadable file requires Geometry Expressions. You can buy the Mathematica application package from Wolfram Research or request a trial version from the developer.
