  • Sexagesimal system:
    (a) 1 right angle =90 degrees =90°
    (b) 1°=60 minutes =60′
    (c) 1’=60 seconds =60″
  • Centesimal system:
    (a) 1 right angle =100 grades =100g
    (b) 1g=100 minutes =100′
    (c) 1’=100 seconds =100″
  • Circular system:
    (a) The unit of measurement is the Radian. One radian is the measure of an angle subtended at the centre of a circle by an arc of length equal to the radius of the circle.
    (b) π radians=180°
