Definition- a deflection angle is the angle which a survey line makes with the prolongation of proceeding line.
Deflection angle vary from 00 to 1800 but never more than 1800.
Deflection angle measured clockwise direction from prolonged survey line is known as right deflection angle.
Deflection angle measured anti-clockwise direction from prolonged survey line is known as left deflection angle.
Procedure-
