  2 The Basics Perpendicular lines meet at 90 o. To draw right angles we use a setsquare. 60 o -30 o 45 o -45 o 60 o 90 o 30 o 90 o 45 o Press is the symbol is the symbol for perpendicular
  
  3 Perpendicular Construction 1 AB C Set Square Construct a line perpendicular to AB through C using a Set Square. C AB C Place Set Square on the line at C. C Draw a line along Set Square from C.Rotate Set Square and move down.Extend the line down.Remove the Protractor.Add the Perpendicular symbol. D CD AB
  
  4 Add the Perpendicular symbol.Rotate Set Square and move down. C Draw a line along Set Square through C. Perpendicular Construction 2 AB C Set Square Construct a line perpendicular to AB through C using a Set Square. A B C Place Set Square on line touching C.C CD AB Extend line down.Remove Protractor. D
  
  5. Add the perpendicular symbol. C AB Draw an semi-circle with centre C and cutting AB. D. Draw an Arc with centre D. the same radius E. Draw an Arc with the same radius and centre E. FC. Draw a line from F through C. Perpendicular Construction 3 AB C Pair of Compasses Construct a line perpendicular to AB through C using a Pair of Compasses. A B C D E F CF AB
