The apparatus used to divide the field of play in various sports can vary depending on the specific sport. For example:
- In soccer, the field is typically divided by lines painted on the grass, including the center line and penalty box.
- In basketball, the court is divided by the three-point line, free-throw line, and the key area (or paint).
- In tennis, the court is divided by the net and lines for singles and doubles play.
- In volleyball, the court is divided by the net and the attack lines.
