the goal line
A transversal
Different pairs of angles have different names.
A transversal is a line that crosses two or more other lines in the plane at different points.
A line intersect is a point on a line where another line or object crosses the line.
The line that crosses the y-axis is called the intercept.
the goal line
it is not a touchdown because the ball never broke the plane.
The x intercept
The point where a line crosses the x-axis is called the x-intercept.
The Asymptote
== == == == When the ball is advanced past the end zone line it is called a touchdown. It is worth 6 points. A touchdown can be scored on offense or defense by any player. A touchdown can also be scored if there is a fumble in the end zone, and the team that scored on that end zone recovers the fumble.
Obligue
It is called the x-intersect.
A transversal
It depends on whether or not he has the ball in his hands when he hits the ground of the endzone. If it is not in his possession, then it is a fumble and can be recovered by a defender. If it is in his hands and he touches the endzone, then it is a touchdown. If he was in possession of the ball when the ball crossed the goal line, it's a touchdown. As soon as the ball breaks the plane of the goal line, the ball is dead and the play is over. Anything that happens after that is irrelevant.
The ball has to be in the touchdown zone. If it is above the zone it is still a touchdown. Take Troy Polamalu's touchdown on Dec,12,2010. He dived, broke the plane of the goal line but he was holding the football above the zone so it counts as a touchdown. In some cases the ref might not count it.
