When is a successful shot worth three points?
Basketball
Measurements and time limits discussed in this section often vary among tournaments and organizations; international and NBA rules are used in this section. The object of the game is to outscore one's opponents by throwing the ball through the opponents' basket from above while preventing the opponents from doing so on their own. An attempt to score in this way is called a shot. A successful shot is worth two points, or three points if it is taken from beyond the three-point arc which is from the basket in international games and in NBA games. A one-point shot can be earned when shooting from the foul line after a foul is made.
