1. 1Compasses at P, radius more than half of PQ: draw arcs above and below PQ
2. 2Same radius from Q: arcs cross the first arcs at two points
3. 3Rule a line through the two crossing points: the perpendicular bisector of PQ is the path

AnswerAcceptable perpendicular bisector of PQ with correct arcs

1. 118 m ÷ 6 = 3 cm on the drawing
2. 2Draw an arc, centre Q, radius 3 cm, reaching the sides of the garden
3. 3Nearer to Q: the side of the bisector containing Q
4. 4Shade the parts on Q's side of the bisector that are outside the 3 cm arc and inside the garden

AnswerCorrect shaded regions
