Statement a: If the whole circle bearing of a line is 270°, its reduced bearing is 90° NW.

The whole circle bearing represents the angle measured clockwise from the north direction. A bearing can be reduced by subtracting or adding 180° depending on the direction. In this case, a whole circle bearing of 270° means that the line is pointing towards the west direction. To reduce the bearing to a more concise notation, we subtract 180° from the whole circle bearing. Therefore, the reduced bearing would be 270° - 180° = 90°. Since the line is pointing towards the west, the reduced bearing is 90° NW (northwest).

Statement b: The boundary of water of a calm water pond will represent a contour line.

A contour line is a line on a map that connects points of equal elevation. In the case of a calm water pond, the water surface is usually at a constant elevation. Therefore, the boundary of the water in a calm water pond will represent a contour line. This contour line will have the same elevation value throughout its length, indicating that the water level is consistent.

Statement d: Back bearing of a line is equal to Fore bearing ±180°.

The fore bearing of a line is the bearing in the direction of the line, while the back bearing is the bearing in the opposite direction. The back bearing can be calculated by adding or subtracting 180° from the fore bearing, depending on the direction. If the fore bearing is less than 180°, we add 180° to get the back bearing. If the fore bearing is greater than 180°, we subtract 180° to get the back bearing.

Therefore, the back bearing of a line is equal to the fore bearing ±180°. This allows us to represent the bearing in both directions using a single angle measurement.

(i) If we combine all the boundaries of water pond, then it will represent contour line.
(ii) The staff intercept will be less when the staff is held nearer to the observation point, in the case of fixed hair stadia tacheometry.
(iii) Back bearing = Fore bearing ± 180
(iv) WCB = 270°, RB = N90°W
