Q. In which of the following transverse method angles are measured by theodolite?

View solution

Q. In transversing by direct observation of angles, magnetic bearing of any one line can also be measured if required.

View solution

Q. Transversing by included angles comes under which of the following?

View solution

Q. __________ at a station is either of the two angles by the two survey lines meeting there.

View solution

Q. Included angles can be measured _________

View solution

Q. All angles are preferred to measure clockwise because of the graduations of theodolite circle increase in this direction.

View solution

Q. A deflection angle is an angle in which a survey line makes with prolongation of back sight.

View solution

Q. Transversing by deflection angles is more suitable for surveys of roads railways, pipe lines etc.
