1. Rough orientation of the plane table – 1

2. The three lines from a triangle of error – 3

3. Drawing lines back through the three control points – 2

4. Select a point in the triangle of error such that ray is equally rotated either clockwise or anti clockwise – 4

5. The points obtained by three rays is the correct location – 5

The correct sequence is:

a. 1, 3, 2, 4, 5

b. 1, 2, 3, 4, 5

## 19. If “H” is the difference in level between end points separated by “L”, then the slope correction is – + – The second term may be neglected if the value of “H” in a 20m is less than ?

a. ½ m

b. 1m

c. 2m

d. 3m

**Answer :- 3m**

If we use any value lesser than 3 and not greater than 3, then answer for slope correction either using the complete formula given above or by eliminating the second term, we will get the same answer. Thus it means that the second term can be eliminated the right answer is 3 and distance kept as 20m.
