NBA = 23' 9" (22' in corner) NCAA = 19' 9" from the center of the hoop. From the wording of the NBA rule book: "d. The three-point field goal area has parallel lines 3' from the sidelines, extending from the baseline and an arc of 23'9" from the middle of the basket which intersects the parallel lines." It has moved a few times in the last 10 years but right now this is where it stands. A free throw line is 13 feet.

The NBA introduced the three point line in the 1979-80 season at a length of 23'9" from the top of the key to a length of 22 feet in the corners. In the 1994-95 season, the NBA changed things so the three point line was a uniform 22 feet from the basket. The distance was reverted to 23'9" in the 1997-98 season and has been there ever since. The 19'9" distance is the distance of the college basketball three point line, which will be changed to 20'9" for the 2008-09 season

If you shoot and make a basket inside the three point line or with your feet on the three point line it is worth two points. If you shoot and make a basket anywhere behind the three point line without your feet on the line it is worth three points. If you get fouled when you are shooting you go to the free throw line to shoot free throws. This is an uncontested, untimed shot that if you make it, it is worth one point.

In the NBA, the three-point line is composed of two lines, parallel to and 3 feet (0.91 m) from the sideline, and a circular arc (centered on the basket) of roughly 120 degrees, which intersects the parallel lines 14 feet from the baseline. [2] The distance of the arc is 23 feet, 9 inches (7.23 m) from the basket. The distance from the line to the basket varies near the sidelines, and is exactly 22 feet (6.71 m) from the basket at its closest point which is 5 feet, 3 inches (1.6 m) from the base line, along an imaginary line parallel to the base line and through the center of the basket

The three-point line is generally an arc at a set radius from the basket. In international basketball, the three-point line is 6.25 meters (20 ft 6 in) from the basket. This distance is also used by most European leagues, as well as the WNBA. In the U.S., college and high school rules for both men and women specify a distance of 19 feet, 9 inches (6.02 m) from the basket. Recreational courts in the U.S., such as those at public parks, also commonly use this distance. This line lies at the same distance from the basket as the top of the key, so the 3 point line coincides with the top of the key at the center point. On May 3, 2007, the NCAA men's basketball rules committee passed a measure to extend the distance of the men's three-point line a foot back to 20 feet, 9 inches (6.32 m). The rule is subject to further approval by an NCAA oversight committee, which is considered likely by coaches and players. If the measure passes, the usage of the new 3-point line will begin with the 2008-09 season. The women's committee, however, decided to keep its line at 19 feet, 9 inches. In the NBA, the three-point line is composed of 2 lines, parallel to and 3 feet (0.91 m) from the sideline, and a circular arc (centered on the basket) of roughly 120 degrees, which intersects the parallel lines. The distance of the arc is 23 feet, 9 inches (7.23 m) from the basket. The distance from the line to the basket varies near the sidelines, and is exactly 22 feet (6.71 m) from the basket at its closest point which is 6 feet, 3 inches (1.91 m) from the base line, along an imaginary line parallel to the base line and through the center of the basket. The line is constructed in this fashion because if it were fixed at the arc distance, there would be very little room to stand inbounds near the baseline. The actual distance of the three-point line at any point along its straight lines can be computed trigonometrically, using the center of the basket and the 22-foot mark as the other 2 points of a right triangle. In order to attempt a three-pointer, a player's feet must be outside the three-point line. At the time of the shot or jump, the player may not be on the line or inside the line, or the basket is considered a two-point attempt; however, the player is allowed to jump from outside the line and land inside the line, as long as the ball is released in mid-air. A referee raises his arm to signal the shot attempt. If the attempt is successful, he raises his other arm and holds up three fingers in both hands to indicate the points scored. The referee must recognize it for it to count as three points. This has often been an issue of contention, as many games have been decided by a last-second three-pointer. In these extreme circumstances, referees have often conferred before deciding on how to rule the shot. Instant replay has sometimes been used, depending on league rules. If a shooter is fouled while attempting a three-pointer and subsequently misses the shot, the shooter is awarded three free-throw attempts. If a player completes a three-pointer while being fouled, the player is awarded one free-throw for a possible 4-point-play.
