It would, indeed. That's where you jumped. When players shoot, they frequently land up within the three-point line, yet it still counts as a three. This is called a "three-pointer" because it can be made from any spot within that area.
A layup is defined as coming from between the legs of the player taking the shot. A 3 point line is located at the top of the key; it is usually marked by a vertical red line. To score a layup, a player must either jump or fall with their body in that direction. If a player doesn't make the jump, then it is a foul and can lead to free throws or another shot for the opposing team.
The NBA began allowing three-pointers in 1979. Before then, there was only one type of field goal: two-points-or-less shots. To this day, most games include some form of three-pointer during timeouts, when a team can substitute one player out. But originally, only men were allowed to play basketball, so all of these shots were really dunks or slamdunks!
In fact, before 1979, there was no such thing as an official dunk! The first dunk recorded in NBA history took place on April 1, 1979.
After releasing the ball, the shooting player may step on or cross the three-point line; the shot will still count for three points. Before shooting the shot, the shooter must have at least one foot on the floor outside of the line. If the player does not meet this requirement before shooting, then it is a foul and the shot cannot be taken.
This rule was adopted in order to encourage teams to play more close-out games and less isolation matchups. It also allows referees to issue technicals if necessary instead of calling time out. Finally, it ensures that no point can be scored when a team has possession of the ball and stands outside of its lane.
The three-point line exists to even out the advantage that height gives a shooter over someone of smaller build. By allowing players to step off the line, the need for any special treatment of center lanes or other adjustments is removed. This means that all areas of the court are treated equally and made available for scoring opportunities.
In addition to being allowed to step off the line, shooters can also reach back with their arms to shoot. The ball must be released before reaching back with your arm, though; otherwise, it's a violation of the rules of basketball.
Finally, players can use their hands to create space for themselves while taking shots.
Any basket made from outside the three-point line is worth three points. If the player does not have at least one foot in this area before shooting, then it is a foul and the shot cannot be taken.
The three-point line extends out from the basket, with its vertex at the midpoint between the top of the key and the bottom of the circle. This means that a three-point shooter needs to be anywhere from 1.5 feet to 2 feet away from the basket in order to shoot successfully.
There are several ways to make three points if you do not shoot. You can get three points for throwing an inbounds ball out of bounds, passing the ball out of bounds, or getting a steal and scoring (if you manage to avoid being called for an illegal touch).
Three points can also be awarded for successful shots taken from behind the arc if the ball goes over the backboard but doesn't go through the net. This happens very often because most players assume that going up against the wall is a sure way to lose your ballgame. Don't make that mistake!
