A hyperbola is an open curve with two branches, the intersection of a plane with both halves of a double cone. The locus of a point which moves in a plane such that the ratio of its distance from a fixed point to its perpendicular distance from a fixed straight line not passing through given fixed point is always constant is called conic section or conic. When one draws a sketch of the graph of a parabola, it is helpful to draw the chord through the focus, perpendicular to the axis of the parabola.
