Basketball is a team sport in which two teams of five players score points by shooting (throwing) a ball through an elevated hoop located on either side of the rectangular court. To advance the ball down the court, players must bounce the ball (dribble) or pass it to a teammate. Points can be earned by shooting a three-pointer (behind the three-point line), a two-point field goal (anywhere not beyond the three-pointer), or a one-point foul shot (after the referee determines a foul). Basketball requires considerable skills related to teamwork, accuracy, ball handling, speed, agility, size and strength. Basketball has become one of the world’s most popular sports.
