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 Five points determine a conic In Euclidean and projective geometry, just as two (distinct) points determine a line (a degree-1 plane curve), five points determine a conic (a degree-2 plane curve). There are additional subtleties for conics that do not exist for lines, and thus the statement and its proof for conics are both more technical than for lines. Formally, given any five points in the plane in general linear position, meaning no three collinear, there is a unique conic passing through them, which will be non-degenerate; this is true over both the Euclidean plane and any pappian projective plane.
