Rushed behind Rushed behind In Australian rules football, a rushed behind occurs when the ball passes through the goalposts and was last touched by a defending player. A rushed behind scores one point against the defending team, but also prevents the attacking team from scoring a goal, worth six points. A rushed behind typically occurs when a defending player touches the ball after it has been kicked and as it heads toward the goal; by touching the ball, the defender ensures that the attacking team scores only one point, rather than the full six. It may be less risky for a defending
Five points determine a conic theorem. Similarly, while nine points determine a cubic, if the nine points lie on more than one cubic—i.e., they are the intersection of two cubics—then they are not in general position, and indeed satisfy an addition constraint, as stated in the Cayley–Bacharach theorem. Four points do not determine a conic, but rather a pencil, the 1-dimensional linear system of conics which all pass through the four points (formally, have the four points as base locus). Similarly, three points determine a 2-dimensional linear system (net), two points determine a 3-dimensional linear system (web), one point determines a 4-dimensional linear system, and
