                    Polar (n.)
                    
                        The right line drawn through the two points of contact of   the two tangents drawn from a given point to a given conic section. The   given point is called the pole of the line. If the given point lies   within the curve so that the two tangents become imaginary, there is   still a real polar line which does not meet the curve, but which   possesses other properties of the polar. Thus the focus and directrix   are pole and polar. There are also poles and polar curves to curves of   higher degree than the second, and poles and polar planes to surfaces   of the second degree.
