Creatively image a question and justification for this answer: in 1987
The question is: Context: Used only in conference play for several years, it was adopted by the NCAA in April 1986 for the 1986 -- 87 season at 19 ft 9 in (6.02 m), and was first used in the NCAA Tournament in 1987. In the same 1986 -- 87 season, the NCAA adopted the three-pointer in women's basketball on an experimental basis, using the same distance, and made its use mandatory beginning in 1987 -- 88. In 2007, the NCAA lengthened the men's distance by a foot to 20 ft 9 in (6.32 m), effective with the 2008 -- 09 season, and the women's line was moved to match the men's in 2011 -- 12. American high schools, along with elementary and middle schools, adopted a 19 ft 9 in (6.02 m) line nationally in 1987, a year after the NCAA. The NCAA used the FIBA three-point line (see below) in the National Invitation Tournament (NIT) in 2018.

Question: when did the three point shot start in high school?
