Q: The direction of a line given by an angle measured clockwise from the north end of a meridian is called:
  • A. parabolic curve
  • B. azimuth
  • C. horizontal curve
  • D. contour
Correct Answer: Option B - Meridian:- The direction of line is defined by the horizontal angle which the line makes with the reference angle line. That reference line is called meridian. • True Bearing/Azimuth:- It is angular measurement of a line with respect to true meridian. • It is also called Azimuth.
B. Meridian:- The direction of line is defined by the horizontal angle which the line makes with the reference angle line. That reference line is called meridian. • True Bearing/Azimuth:- It is angular measurement of a line with respect to true meridian. • It is also called Azimuth.
