Billiards 8-Ball Rack Setup Diagram - Standard Triangle Formation #3071010 (License: Personal Use)

This diagram illustrates the official 8-ball rack configuration used in competitive and recreational pool games. The 15 object balls are arranged in a tight equilateral triangle, with the 8-ball positioned at the center of the third row, and the two back corners occupied by one solid and one striped ball (as per BCA rules). The apex ball is typically the 1-ball, though not mandatory in all rule sets.

Used on pool instruction websites, rule guides, tournament resources, and beginner tutorials to demonstrate proper ball setup before the break shot; matches user intent for learning or verifying official rack standards.
