Focal chord
WebAnswer: Consider the parabola: The distance between the vertex and the focus, measured along the axis of symmetry, is the "focal length". The "latus rectum" is the chord of the parabola which is parallel to the directrix and passes through the focus. In fact the “latus rectum” used to be calle... Webfocal chord.

Conclude that the directrix is tangent to the circle. The chord of the parabola which passes through the focus is called the focal chord. Any chord to y2 = 4ax which passes through the focus is called a focal chord of the parabola y2= 4ax. Let y2= 4ax be the equation of a parabola and (at2, 2at) a point P on it.
