Steps are given to find the axis of a parabola. Arrange the steps.i. Draw a perpendicular GH to EF which cuts parabola.ii. Draw AB and CD parallel chords to given parabola at some distance apart from each other.iii. The perpendicular bisector of GH gives axis of that parabola.iv. Draw a line EF joining the midpoints lo AB and CD.
