# Geometry of billiards

## Is billiards a geometry?

A game of billiards can be both fun and educational. From simple geometry and shapes to more advanced physics, teachers and parents alike can use billiards to make science relatable and understandable.

## How do you calculate an angle in billiards?

A simple way to visualize and estimate cut angles is to imagine an analog clock face (or use one on your wrist). If noon (12) is straight (0°), 11 and 1 are at 30° (1/2-ball hit), 10 and 2 are at 60° (about an 1/8-ball hit), and each minute is 6°.

## How does Billiards use reflection?

The law of reflection : the angle of incidence equals the angle of reflection . “If you shoot the ball so that it hits one of sides of the table head-on (its trajectory forming a right angle with the side), then it will return along the same trajectory it arrived on, but travelling in the opposite direction.

## What math is used in pool?

The most popular game on the pool table is “8 ball” but there are other games, too. No matter which game you play, understanding the underlying rules of geometry, trigonometry, and physics, will help you sink a ball into a pocket.

## Why do snooker players wiggle their finger?

Many do it because when you tap a finger (mostly middle), it firms the bridge hand especially the back part of the bridge on the table. Stabilizes the bridge hand further to avoid shaky delivery of the cue. It’s a good way to ensure your bridge is stable.

## What do the diamonds mean on a pool table?

The diamonds are an aid to banking. If you are attempting a bank shot, find the diamond that will make the object ball bounce off the rail and drop into the desired pocket. The angle that the ball entered the rail is the angle that it left the rail – mirrored angles.
