WebThe angle between the adjacent traverse lines is measured using the chain angles concept. Chain traversing is performed in areas such as ponds etc. where it is difficult to adopt triangulation. The chain angles concept is nothing but finding the angle between two adjacent sides by establishing the third side using tie stations. This angle ... WebAngles measured are interior angles if traverse is run in anticlockwise direction and theoretical sum is equal to (2n -4) x 90º Angles measured are exterior angles if traverse is …
