AG Mechanics CDE Practice Exam

The rectangular survey system refers to lines running north and south every 6 miles as:

1. Principal Meridians

2. Range Lines

3. Baseline

4. Township Lines

The correct answer is: Principal Meridians

The answer is not B, Range Lines. Range lines refer to lines running east and west every 6 miles (or 1 mile in some areas) in the rectangular survey system. Option C, Baseline, is also incorrect as this refers to an east-west reference line, not north-south. Similarly, option D, Township Lines, is incorrect as these refer to lines running east-west every 6 miles within the rectangular survey system. These options are not the correct answer because they do not refer to the specific lines mentioned in the question, which are the lines running north and south. These lines are referred to as Principal Meridians, making answer option A the correct choice.
