What does the bearing of a line measure?

• A. The distance from the line to true south
• B. The vertical angle of the line
• C. The horizontal angle between direction of the line and true north
• D. The curvature of the line over distance

Answer: (C)

The bearing of a line specifically refers to the horizontal angle measured clockwise from a reference direction, typically true north, to the line in question. This measurement provides a clear indication of the direction in which the line is oriented relative to true north, making it essential for navigation, surveying, and mapping. In this context, bearing is crucial for determining the precise alignment of a geographical feature or infrastructural element. Understanding bearings allows professionals to communicate directional information effectively and ensures that designs, layouts, or routes can be accurately replicated or followed. The other options describe attributes that are not related to the definition of bearing. While the distance from the line to true south may offer some directional information, it does not align with the standard definition of bearing as an angle from true north. Similarly, while the vertical angle of a line pertains to its slope or incline relative to the horizontal plane, it does not reflect a bearing. Lastly, curvature relates to the shape of the line over a distance and does not pertain to the angular measurement that a bearing signifies.
