⸙Answer ⸙

Principal of chain surveying is triangulation

The principle of chain surveying is triangulation. This means that the area to survey is spilled into a number of small triangles which should be well-conditioned. In chain surveying, the side of the triangles are measured directly from the field by chain or tape, and no angular measurements are used.
