Question

What is the purpose of measuring the horizontal angle by repetition method.

Answer 1

India is often called a subcontinent because it is a distinct landmass, not just a country. While it has many features of a continent, it is not as big as one, so is not considered a continent.

Answer 2

In surveying, the repetition method is used to improve precision and accuracy of measurements of horizontal angles .The same angle is measured multiple times, with the survey instrument rotated so that systematic errors tend to cancel .The arithmetic mean of these observations gives true value of an angle.
