It's off the defender who blocked the shot.
Yes
no
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.
When a player throws the ball onto the backboard and a person catches it after it hits the backboard
Yes, it is. As long as the ball does not hit the back of the backboard or the shot clock, the shot is valid.
Only if your the person who did not shoot the ball
No if it was airball and nobody touched it it would be traveling. Once it has it the backboard its anybody's ball.
If the ball goes off the rim and over the backboard then it is out of bounds. If it goes off the rim and hits the top of the backboard but falls back in play on the front side of the backboard, then it isn't out of bounds.
yes
no
no, and I'm guessing you mean basketball rules and regulations ahah.
The ball is out because the back of the backboard (goal) is outside of the court.
