Question

Draw a line segment of length 7 cm. Draw its perpendicular bisector, using ruler and compasses.

Answer 1

Steps of construction:

1. Draw a line segment AB = 7 cm.
2. With A as centre and radius more than half of AB, draw arcs, one on each side of AB.
3. With B as centre and same radius as before, draw arcs, cutting the previously drawn arcs at X and Y respectively.
4. Now join XY, meeting AB at O. Thus, XY is the perpendicular bisector of AB.
