To construct a perpendicular to a line(L) from a point (P) outside the line, steps are given in jumbled form.Identify the fourth step from the following
1) Draw line PQ
2)Draw a line L and consider point P outside the line
3)Take P as a center, draw 2 arcs on line L and name it as points A and B respectively
4)Taking A and B as a center one by one and keeping the same distance in compass, draw the arcs on other side of the line.The point where these arcs intersect name that point as Q
