Notes
B2: B2 for a fully correct perpendicular bisector with 2 pairs of intersecting arcs shown
(the line and the arcs can intersect on or within the overlay guidelines)
(B1 for 2 pairs of intersecting arcs and no perpendicular bisector drawn
or
for a correct bisector perpendicular drawn within or on guidelines but no arcs or insufficient arcs
or
one pair of intersecting arcs and perpendicular bisector drawn on just one side of \(AB\))
