In theodolite surveying, measurement of deflection angle between 0° - 180° but in closed traversing sum of all deflection angles = 360°.

In the Clockwise direction, the summation of deflection angles gives the sum of exterior angles and in an anti-clockwise direction, interior angles.

So, the difference comes out to be 360°.
Sum of exterior angles-sum of interior angles of any closed traverse=360°.

The summation is 0 and the difference is 360. We consider left-hand angles as negative and right-hand angles as positive.

So, obviously, their algebraic summation is 0 and their algebraic difference is 360.

I think 180° is correct.

@Deepanshu,

Isn't it a summation but here they are asking difference, please explain?

What is the open traverse of deflection angle?

Deepanshu said:   4 years ago
In closed traverse, the summation of all deflection angle is 360 degree.

180 left hand + 180 on right hand = 360°.

How explain?

360°-0°=360°.
