What is the purpose of the three-point line in basketball?

The purpose of the three-point line in basketball is to define the distance from which a shot is worth three points, distinguishing it from shots made within the line, which are worth two points. This line creates a strategic element in the game, encouraging players to develop a diverse range of shooting skills and allowing for a greater variety of offensive plays. A successful shot beyond this line rewards the team with an additional point, making it an essential aspect of scoring in modern basketball.

The line also influences defensive strategies, as teams may focus on contesting shots from beyond the arc to limit scoring opportunities. Additionally, the existence of the three-point line contributes to the overall pace and style of play, as teams may rely on perimeter shooting to spread the floor and create driving lanes for other players.
