Explanation Parabola is a set of all points in the plane which are at fixed distance from the fixed point called focus and fixed line called directrix. There are four types of parabolas called right opened, left opened, upward and downward. The distance between the focus and the vertex is a . The left opened parabola, y 2 = 4 a x is shown below in Figure 1. From Figure 1, observe that the line through the focus and perpendicular to the directrix is called axis of symmetry. The line segment joining two points ( a , 2 a ) a
