On the Beach
Place a cone or stand in the middle of the group.
Instruct the group to stand 5 metres away from me
How could we use the rope?
Sketch diagram
Place 2 cones roughly 20 metres away from one another or 2 teachers
stand roughly 20 metres apart.
Instruct the group to stand equidistant away from both cones
How could we use the rope?
Sketch diagram
Place 2 pieces of rope as two lines meeting at a point. Rope needs to be
more than 10 metres long.
Instruct the group to stand equidistant away from both lines.
How could we use the rope?
Sketch diagram
Use rope to make a 5 metre by 5 metre square.
Instruct the group to stand 1 metre away from the perimeter of the
square
How could we use the rope?

Loci of a point
Equidistant from 2 points
Equidistant from 2 lines
Loci of shapes
Construction using a compass and a ruler
(Always keep the compass the same size as you startered)
Step 2 – make an arc above and below the line
Step 3 – Repeat from the other end of the line
Try it!!!!!
Finished, the 2 lines are 90 degrees to each other
Step 2 – Draw an arc on both lines
Step 3 – move the compasses to each of the arcs on the lines in turn
Step 4 – Make another arc in the general area of the bisection
Step 5 – Repeat from the other arc
Step 6 – Now draw a line from the end of your line through the arcs
Try it!!!!!!!!!!
Extension – Try 
Constructing a perpendicular from any point to a line

Constructing a loci equidistant from 2
points
