Draw a line segment of length 7cm. Draw its perpendicular bisector,using ruler and compasses.
Steps of construction:
(i) Draw a line segment AB of 7cm using the ruler.
(ii) Draw arcs of more than half the length of AB taking A as centre on both sides of line AB.
(iii) Draw arcs of more than half the length of AB taking B as centre on both sides of line AB which cutting the previously drawn arcs at X, Y respectively.
(iv) Join XY which is the perpendicular bisector of AB.
