In college basketball it is 20 feet 9 inches
The Southern conference tested the line in the late 70s.
It was extended in 2007
Ronnie Carr of Western Carolina made college basketball's first 3-point shot in 1980. Chris Ford of the Boston Celtics made the NBA's first 3-point shot in 1979.
1979, the NBA first adopted it on October 12th. Chad Donahue made the NBA's first three point basket
The NCAA's Southern Conference became the first collegiate conference to use the three-point rule, adopting a 22-foot line in 1980
The 3 point shot was added to college ball in 1987, I believe. At 19'9" it is shorter than the International version and the NBA version at 23'9"
i have no idea
Yes because you have to prepare for the NBA by shooting at the three point line.
Ronnie Carr sank the first three pointer in 1980.
