Which of the following statement(s) is/are true for the 'Method of Reiteration' for measuring the horizontal angles? i. This method is useful when more number of angles are to be measured at one point ii. The horizontal angle is measured a number of times and the average value is taken
- AOnly (i)Correct
- BOnly (ii)
- CBoth (i) and (ii)
- DNeither (i) nor (ii)
Solution
Concept
Reiteration vs repetition
Step-by-step solution
1. Reiteration is used when several angles are to be measured at one station (i true). 2. Measuring one angle several times by accumulating it on the vernier and averaging is the method of repetition (ii false for reiteration).
Explanation
Statement (ii) describes repetition.
Why the other options are wrong
Options with (ii) mix up the methods.
Shortcut
Reiteration = many angles; repetition = one angle repeated.
Correct answer: A) Only (i)
