Q: In which of the following surveying method. All triangles formed by survey lines are considered as plane triangles.
  • A. Plane surveying only
  • B. Geodetic surveying only
  • C. Both Plane surveying and Geodetic surveying
  • D. None of these
Correct Answer: Option A - Plane surveying– In plane surveying, the mean surface of the earth is considered as a plane and spheroidal shape is neglected. •All triangles formed by surveys lines are considered as plane triangles. Geodetic surveying– In geodetic surveying, the shape of the earth is taken into account. • All lines lying in the surface are curved lines and the triangles are spherical triangle.
