If the ball bounces off the backboard or rim and you catch it before it hits the ground it counts as a rebound.
only if the ball comes off of the rim or backboard of the basket
If a player shoots and it doesn't hit the backboard or rim, and they catch it before it hits the floor, it's a travel. The ball either has to: a) Hit the rim or backboard. b) Hit the ground before the player can retain possession again.
rebound
If it's an airball then no. If it just hits backboard then you aren't supposed to be able to but I see certain players do it all the time.
Yes, as long as the ball hits some part of the goal, its not traveling.
no
yes you can. in fact there is a recent, and very popular event where Kobe Bryant threw the ball off the backboard, followed it in and dunked it. i believe there is a video on youtube about it.
Yes
no, and I'm guessing you mean basketball rules and regulations ahah.
Preferablely facing the basket, but if you are boxing the defender out focus on where the ball may bounce off the backboard so you can get there first
Out of bounds, same if it hits the very top or back of the backboard!
