Q1.	The additional lines which are measured to show the correctness of the chain surveying are called:
A.	check clines [Wrong Answer]
B.	proof lines [Wrong Answer]
C.	tie lines [Wrong Answer]
D.	all of these. [Correct Answer]
View Answer 25 -7 Explanation:- Answer : D Discuss it below : Himanshu Gupta Said on 2019-06-24 09:24:36 given ans is correct. check lines are also calle as proof lines. Tie lines helps to check the accuracy of surveying and to locate the interior details. hence the answer is 'D' !!
