Perpendicular distance Offset Side distance Perpendicular offset 2 / 22 What triangles are generally preferred to get good results in plotting? Obtuse angled Equilateral Isosceles Acute angle 3 / 22 As far as possible main survey lines should pass through the obstacles to get know how many obstacles present. True False 4 / 22 How many kinds of obstacles of chaining are there? 2 3 4 5 5 / 22 When it is possible to chain round the obstacle, i.e a pond, hedge etc. This case comes under which among the three kinds of obstacles to chaining? obstacles to chaining but not ranging obstacles to ranging but not chaining obstacles to levelling obstacles to ranging and chaining 6 / 22 Both ends of the line may not be visible from intermediate points on the line. This case comes under which among the three kinds of obstacles to chaining? obstacles to chaining but not ranging obstacles to ranging but not chaining obstacles to levelling obstacles to ranging and chaining 7 / 22 If we select two points A and B on either side of the obstacle and equal perpendiculars AC and BD are set out. Then AB is equal to? AC CD DA BD 8 / 22 What is the direction of line relative to a given meridian? Length of a line Bearing of a line Slope of a line Reciprocal of slope of a line 9 / 22 Which line passes through true north and true south? True Meridian Arbitrary Meridian Magnetic Meridian Dip 10 / 22 Which meridians are used to determine the relative positions of the lines in a small area? True Meridian Magnetic Meridian Arbitrary Meridian All meridians 11 / 22 Convert 22°30′ whole circle bearings to quadrant bearings? 22°30 180 – 22°30 360 – 22°30 270 – 22°30 12 / 22 Which of the following is the most convenient and portable instrument for direct measurement of directions?
