After all, the rule is that a touch down occurs when the ball breaks the plane of the goal line. So you can imagine a plane that extends upwards from the field, perpendicular to it. If the ball (a point) hits this plane or passes through it and is is possessed by the team, then it is a touch down.
In both Algebra and Geometry we've been talking about these terms:
Have a happy and safe Thanksgiving!
