In basketball, a shot's point value depends on the location the player makes the shot from. The most valuable shots are worth three points and are possible only when the scoring player is standing outside the three-point line, which forms a semicircle around the opposing player's basket. For such points to count, the player must have two feet on the ground before making the shot attempt.
Players may also attempt to score from inside the three-point arc, though these shots are only worth two points. Because receipt of these points depends on ownership of the basket, not on the team identity of the player, it is possible for a player to accidentally send the ball into his or her own team's basket and thus score two points for the opposing team.
Single-point scores only occur in basketball during a free throw. These take place after a player commits a personal foul on a player who is making an attempt to shoot. When the referee grants the free throw, the player granted the shot stands behind the free throw line, located inside the opponent's three-point arc and directly in front of the basket. He or she makes the attempt unimpeded by an opposing player. Depending on the offense, the player may have one to three such shots, each of which is worth one point if it is successful.
