Goal (sport) Nets are required. The following games have more than one possible method of scoring where the goal is the primary method, "i.e." the method that scores the most points. In most cases the score is shown as the number of goals, plus the number of secondary scores (usually 1 point), plus the total number of points. The side with the higher number of total points is the winner. In Australian rules football a goal is scored when the ball is kicked by an attacking player completely between the goal posts. The ball may not contact or pass over the goal
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
