True or False: At the taking of a corner kick, the ball must entirely leave the corner area before it is in play.

The statement that the ball must entirely leave the corner area before it is in play is false. According to the Laws of the Game, the ball is considered in play as soon as it is kicked and clearly moves. This means that it does not have to leave the corner area entirely before being deemed in play.

Understanding this allows referees and players to manage the game flow effectively. In practical terms, this means that as soon as the player takes the corner kick and the ball moves, whether from within the corner arc or as it crosses over its boundaries, the game resumes and other players may react accordingly.

Knowing that the corner area rules differ from others, like how a goal kick or throw-in is executed, is crucial for proper officiating and understanding the game's mechanics.
