Question

construct a line segment of length =10cm and draw it's perpendicular bisect

Answer 1

first draw a line segment AB of length 10cm. then A as center draw an arc which hav length more than 5cm .similarly with B as center draw arc and join the two points where the two arcs touches each other . it is line which bisect the line in 90 degree

Answer 2

Draw a line segment PQ of 10 cm Taking P as centre and radius more than 5 cm draw arcs both in upward and downward direction Similarly draw two arcs from Q . join the points of intersection to obtain the perpendicular bisector
