1. Draw a line segment \(\overline{PQ}\) = 6.4 cm
2. Set the compasses as radius with more than half of the length of \(\overline{PQ}\).
3. With A as centre, draw arcs below and above the line segment.
4. With the same radius and B as centre draw two arcs above and below the line segment to cut the previous arcs. Name the intersecting points of arcs as X and Y.
5. Join the points X and Y. So, the line l is the perpendicular bisector of AB.
Hence l is the required perpendicular bisector of AB which meets at M.
