Two-pointers are a type of basketball shot that is worth two points. They are taken from behind the three-point line, which is the arc that circles the basket and is located at a distance of 6.25 meters from the basket. The term 'two-pointers' is derived from the fact that shots taken from within the three-point line are worth two points. The term 'colons' is used to refer to two-pointers because it is a punctuation mark that looks like two dots side by side, similar to the two points that are scored when a two-pointer is made.
