(i) Draw a line segment AB of 5cm
(ii) Draw the perpendicular bisectors of AB
(iii) Draw an arc which intersects the perpendicular bisectors at point O will be required center.
(iv) With center O and radius OA draw a circle. No, we cannot draw a circle of radius 2cm passing through A and B because when we draw an arc of radius 2cm with center A, the arc will not interest the perpendicular bisector and we will not find the center
