After a free throw which is not followed by another free throw, the ball must be put in play by a throw-in:
ART. 1 . . . As after a field goal, as in 7-5-7, if the try is for a personal foul other than intentional or flagrant, and is successful.
ART. 2 . . . By any player of the free-thrower’s team from out of bounds at the division line on the side opposite the scorer’s and timer’s table if the free throw is for a technical foul.
ART. 3 . . . By any player of the free-thrower’s team from the out-of-bounds spot nearest the foul if the free throw is for an intentional personal foul or flagrant personal foul.
