At the professional level, the three-point arc rests 23 feet, 9 inches from the center of the hoop. It is shorter in high school and college play, where it sits 19 feet, 9 inches and 20 feet, 9 inches, respectively.
The three-point shot did not always exist on the basketball court. It was brought to NBA courts for the 1979 to 1980 season and introduced to the college game for the 1986 to 1987 season. High school play was the last to include the three-point shot, adding it for the 1987 to 1988 season. While the inclusion of the shot was both welcomed and frowned upon, those on both sides agree it has changed the game dramatically.
