Q: In geodetic surveying, sum of all the internal angles (degree) should be .........
  • A. equal to 180
  • B. equal to 360
  • C. greater than 180
  • D. less than 180
Correct Answer: Option C - Geodetic surveying is a type of surveying in which the curvature of the earth is taken into account while calculating reduced levels, angles, bearings and distances. This type of surveying is usually employed for large survey works. Survey works upto 250 square km. are treated as plane and beyond that are treated as geodetic. The sum of angle of triangles in the geodetic survey is grater than 1800 and not more than 540⁰.
