The "Goal Line" is a critical boundary in various sports, particularly in football and rugby. It marks the area where a team must advance the ball to score a goal or a try. In American football, the goal line is located at the end of the field, and crossing it with the ball results in a touchdown. In soccer, the goal line is the line that runs along the width of the field at each end, where the goalposts are situated. A goal is scored when the entire ball crosses this line between the posts and beneath the crossbar. The goal line is essential for determining scoring in these sports.
