The following steps illustrate the formation of a perpendicular bisector.
True
(1) Draw a line.
(2) Take a compass and adjust it in such a way that the length measures more than length of 12AB
(3) Draw an arc with A as the centre. Draw an arc with B as the centre.
They meet at point P and Q.
(4) Join PQ.
PQ is the perpendicular bisector of AB.
