The aiming skill of billiards depends on diligent practice to form feelings, but it also depends on correct aiming methods, which are based on the principles of physics and mathematics and can be traced back.

Here are some illustrations of billiards aiming skills:

1, aiming diagram of cue ball, target ball and bag center not in a straight line (eccentric ball):

2. Pay attention to the "aiming point" and "collision point" in the figure below. Draw a straight line (yellow line in the figure) that passes through the aiming point and is perpendicular to the line connecting the centers of the two balls. If the cue ball is located anywhere in the photocopying area in the figure, the target ball can be put into the bag.

3. All cue ball positions as shown in the figure below can make the target ball enter the bag.

4. Regarding aiming to turn right, the following figure is a schematic diagram of aiming to turn right.

5, need to pay attention to the wrong aiming method.

6. Be sure to pay attention to the aiming point at this time. You can't aim at the ball incorrectly as above, but you should press the aiming point without rotating, and then translate and hit the right side of the cue ball, about aiming to the left. The following figure is a schematic diagram of the aiming point when adding left rotation.

7. The following picture shows the wrong aiming method for the same reason as the right turn above.
