A missed shot?? OR a rimmer, or a brick (most commonly called a brick)
No, it is not considered out of bounds if the ball hits the side of the backboard. Unless it bounces off the side of the backboard and then out of bounds before you or someone else can catch it.
Yes, and it's out-of-bounds.
If the ball bounces off the backboard or rim and you catch it before it hits the ground it counts as a rebound.
it is called a air ball
Yes, as long as the ball bounces back towards the free throw line. There is a plane not only on the top of the back board but on the sides as well and if the ball bounces fully past it on the top or the side it is considered out of bounds.
It is called a lip out.
The basketball backboard is there to show ppl where to shot the ball to get it in.
