How must "Change in Direction" between lines be represented on a drawing?

The representation of a "Change in Direction" between lines on a drawing is essential for accurately conveying the geometry of a land survey. Using angles, bearings, or azimuths provides a precise mathematical description of the direction in which each segment of the line proceeds.

Angles can delineate the exact degree of turn from one line segment to the next, helping to clarify how much the direction has changed. Bearings are used to specify directions based on compass points, while azimuths provide a numerical measurement of the angle in degrees from a north reference. These methods ensure that anyone interpreting the drawing can clearly understand how each line relates spatially to the others.

This method of representation is favored over the other options. Different colors may enhance visual appeal or distinguish features, but they do not convey the necessary precision required in surveying. Curved lines typically indicate continuous change rather than abrupt changes in direction, which is not applicable here. Simple arrows could suggest direction but fail to provide the detailed numeric or angular information required for a comprehensive understanding of directional changes in the context of survey drawings.

Thus, the use of angles, bearings, or azimuths stands out as the most accurate and representative way to depict changes in direction between lines in land surveying.
