| construction | 2 | M1 for a pair of arcs or a single arc, centre C, that cut line AB and at least one pair of arcs not at C within guidelines A1 for perpendicular within guidelines with appropriate construction arcs OR M1 for an arc, centre A radius AC and an arc centre B radius BC. The two arcs must intersect below AB A1 for perpendicular within guidelines with appropriate construction arcs (SC If M0 scored, B1 for correct perpendicular line within guidelines) |
