    • ( 4 ) The true or geographical meridiams through the various stations

    • 1) are parallel
    • 2) converge to the poles
    • 3) converge from north pole to south pole
    • 4) converge from south pole to north pole
    • Discussion in forum
      Answer : 2) converge to the poles
      Solution : The true or geographic meridian is a line in which the plane passing through the given point and the north and south poles intersect the surface of earth.
      - The direction of a true meridian is invariable. The true meridians through the various stations are not parallel, but converge to the poles.
      - However, for ordinary small surveys, they are assumed to be parallel to each other.
      - The horizontal angle between the true meridian and the line is called true bearing of a line. It is also known as Azimuth.

    • ( 5 ) The correction for sag is

    • 1) always additive
    • 2) always subtractive
    • 3) always zero
    • 4) sometimes additive and sometimessubtractive
    • Discussion in forum
      Answer : 2) always subtractive
      Solution : When the tape sags between points of support, it takes the form of a catenary. The correction for sag Cs is always subtracted from observed distance and is given by Cs = W2L/24P2
