1) Offset angle taken in chain survey is ✓ any angle
2) The correct relation between fore bearing and back bearing in compass survey is
✓BB= FB+l-180°
3) Chain surveying is used for small area in
✓ fairly level ground
4) An area can be completely defined with the linear measurement only if
✓ it is enclosed by a triangle
5) To determine the area of of plot it should be divided into geometrical figure with all its side known should be
✓parallelogram
6) During the setting out of small building curved wall line is out from known centre and radius of curvature by using
✓ string and measuring tape
7) Dumpy level is most suitable when
✓ many reading are to be taken from a simple setting of instrument
8) The method for linear measurement completely by means of observation through instrument avoiding the use of measuring tape is
✓indirect method
9) The principle of plane tabling is based on the fact that the line joining the point on the plane table have relationship with the corresponding line joining the ground points while working it is station as
✓ parallel to each other
