In the Bowditch (compass) rule for balancing a closed traverse, the correction to each latitude or departure is:
Choose the correct answer
Proportional to the angle at the traverse station
Proportional to the length of the corresponding survey line
Equal for all sides
Proportional to the latitude or departure of that line
Correct Answer
B. Proportional to the length of the corresponding survey line

Bowditch rule: correction to latitude (or departure) = (error in latitude / sum of lengths) x length of that line. This distributes error proportionally to side length. Transit rule distributes proportional to arithmetic sum of latitudes/departures (used when angles are more accurate than distances).
