90-Degree Rule (Tangent Line)

The 90-Degree Rule (Tangent Line) Aiming System is a straightforward approach to aiming in billiards that utilizes the concept of angles and tangent lines. This method helps players understand how to direct the cue ball towards the object ball based on a 90-degree angle. Here’s how to use the system effectively:

Steps to Use the 90-Degree Rule (Tangent Line) Aiming System:

• Identify the Pocket:

  • Determine which pocket you want the object ball to go into.

• Locate the Object Ball:

  • Position yourself so you have a clear line of sight to both the object ball and the target pocket.

• Visualize the Tangent Line:

  • Imagine a line that runs from the center of the object ball to the pocket.

  • The tangent line represents the path the object ball will follow after being struck by the cue ball.

• Determine the Contact Point:

  • Visualize where the cue ball needs to hit the object ball to send it on the tangent line toward the pocket.

  • This is typically the edge of the object ball that is opposite the pocket.

• Establish the 90-Degree Angle:

  • Identify the point where the tangent line intersects the edge of the object ball.

  • The aim is to strike the object ball at this contact point, creating a 90-degree angle with the line leading to the pocket.

• Align Your Cue Stick:

  • Position your cue stick to line up with the contact point on the object ball.

  • Make sure your cue stick is straight and aimed precisely at this point.

• Focus on the Shot:

  • Keep your eyes on the contact point as you prepare to take your shot.

  • This focus helps ensure accuracy and reduces distractions.

• Cue Ball Contact:

  • Deliver a smooth stroke aimed at the cue ball’s center (or slightly above or below for spin).

  • Maintain a consistent speed to control the distance the cue ball travels after the shot.

Additional Tips:

• Practice Visualization:

  • Spend time visualizing the tangent line and the contact point during practice sessions to reinforce your aiming skills.

• Use Different Angles:

  • Practice shots from various angles and distances to become comfortable with applying the 90-degree rule in different situations.

• Incorporate Spin:

  • Be mindful of how applying spin affects the cue ball’s path. Adjust your aim slightly if using top, bottom, or side spin.

• Stay Relaxed:

  • Keep your grip and stance relaxed to promote a smooth, controlled stroke.

• Drill for Consistency:

  • Set up drills focusing on tangent line shots to help internalize the 90-degree aiming method.

The 90-Degree Rule (Tangent Line) Aiming System simplifies the aiming process by emphasizing visualizing angles and direct lines. By practicing this system, players can improve their accuracy and consistency in making successful shots.
