This makes them similar triangles: same shape, different sizes. Then, hit the cue ball into the rail at the point where the 2 lines meet, which will guarantee that it bounces off and hits the other ball. The perpendicular is a perpendicular because we have defined it that way. Pool table math is a common feature of a lot of geometry textbooks. Creative Commons Attribution/Non-Commercial/Share-Alike.

We also show how to calibrate your hand so you can judge these shots (and the corresponding cut angles) fairly accurately. So imagine this is our approach Aim for the center of the ghost ball. This means that the kinetic energy in their motion is almost completely preserved, and very little of it dissipates into heat or other energy sinks. It seems possible to me that a student would just alter the point of reflection bit by bit until the shot was successful. Referencing the diagram, the angle to aim at is y=ax/ (a+b) if they are not the same distance from the rail (the top). Locate the target point on the object ball, the furthest possible point on the ball from the center of the pocket drop. What we were investigating in the Pool Table Problem was the number of bounces found in a rectangle until it hits a corner.
