A three-point field goal (also 3-pointer, three, or triple) is a field goal in a basketball game made from beyond the three-point line, a designated arc surrounding the basket. A successful attempt is worth three points, in contrast to the two points awarded for field goals made within the three-point line and the one point for each made free throw.
The distance from the basket to the three-point line varies by competition level: in the National Basketball Association (NBA) the arc is 23 feet 9 inches (7.24 m) from the center of the basket; in the International Basketball Federation (FIBA), the Women's National Basketball Association (WNBA), the National Collegiate Athletic Association (NCAA) (all divisions), and the National Association of Intercollegiate Athletics (NAIA), the arc is 6.75 m (22 ft 1.75 in) from the center of the basket; and in the National Federation of State High School Associations (NFHS) the arc is 19 ft 9 in (6.02 m) from the center of the basket. Every three-point line becomes parallel to each sideline at the points where each arc is a specified distance from the sideline. In both the NBA and WNBA, this distance is 3 feet (0.91 m) from the sideline; as a result, the distance from the center of the basket gradually decreases to a minimum of 22 feet (6.7 m). FIBA specifies the arc's minimum distance from the sideline as 0.9 meters (2 ft 11 in), resulting in a minimum distance from the center of the basket of 6.6 meters (21 ft 8 in). The NCAA and NAIA arc is the same distance from the center of the basket as the FIBA arc, but is 3 feet 4 inches (1.02 m) from each sideline because the North American court is slightly wider than the FIBA court. In 3x3, a FIBA-sanctioned variant of the half-court 3-on-3 game, the same line exists, but shots from behind it are only worth 2 points with all other shots worth 1 point.[1]
