A parabola is the locus of points that are equidistant from a fixed line and a fixed point not on that line.

The fixed point is known as focus of the parabola and the fixed line is known as directrix of the parabola.

Procedure:

1. Draw the given directrix d and focus F and locate a point D1.

2. Locate a point P1 which is the mid-point of FD1. The point P1 will be the vertex.

3. Locate the points P1, P2, and P3 such that D1<
