Question:A transit is oriented by setting its vernier A to read the back azimuth of the preceding line. A back sight on the preceding transit station taken and transit is rotated about its vertical axis. The vernier A reads

1.The directions of plumb lines suspended at different points in a survey are not strictly parallel

2. In surveys of small extent, the effect of curvature may be ignored and the level surface of the earth is assumed as horizontal

3.In surveys of large extent, the effect of curvature of the earth must be considered
