For a closed traverse, the algebraic sum of the exterior angles, measured consistently in one direction, is:
Correct answer: D. 360°
- A. 180°
- B. 270°
- C. (n − 2) × 180°
- D. 360°
Explanation
A complete circuit turns through one full angle, so the algebraic sum of consistently measured exterior angles is 360 degrees. The expression (n − 2) × 180 degrees applies to the interior angles of an n-sided polygon.

About Surveying
Surveying covers measurement of distances, angles and elevations, traversing, levelling, contouring, plane table work, theodolites, total stations and basic photogrammetry. It includes error adjustment, coordinate calculations, area and volume determination, and the distinction between accuracy and precision, as well as between temporary and permanent adjustments.
