- 1
  
  ⇔
  
  Use your pencil and ruler to draw one edge to the required length.
- 2
  
  ⇔
  
  Set the width of the pair of compasses to the length of the drawn edge.
- 3
  
  ⇔
  
  With the needle point on one end of the line segment, draw an arc.
- 4
  
  ⇔
  
  Put the needle point on the other end of the line segment.
- 5
  
  ⇔
  
  Check the width of the pair of compasses is still the length of the edge.
