Choose the correct statement. a) The sum of the measured interior angles should be equal (2N - 4) right angles. b) If the exterior angles are measured, their sum should be equal to (2N + 4) right angle. Where N is the number of sides of the traverse. Correct Answer Both the statement (a) and (b) are true

Concept:

Closed traverse:

When the lines form a circuit that ends at the starting point, it is known as a closed traverse. There should be a minimum of 3 no. of sides for closed traversing. 

Properties of closed traverse:

The sum of measured interior angles should be equal to (2N - 4) × 90°, where N=number of sides of the traverse.

The sum of measured exterior angles should be equal to (2N + 4) × 90°, where N=number of sides of the traverse.
