Constructing a perpendicular bisector

Constructing a perpendicular bisector.

  • Use a sharp pencil, ruler and compasses or protractor as specified.
  • Keep the arcs and guide marks that show how the construction was made.
  • Check the required lengths and angles without erasing the construction.
