A triangle is said to be well conditioned when no angle in it is less than 30' or greater than 120'.An equilateral triangle is considered to be the best-condition or ideal triangle[Figs 2.1 (a) and (b) ].
We'll-conditioned triangles are preferred because their apex points are very sharp and can be located by a single 'dot'. In such a case, there is no possibility of relative displacement of the plotted point.
A triangle in which an angle is less than 30' or more than 120' is said to be i'll conditioned[Fig. 2.1(C)].

I'll-condoned triangles are not used in chain surveying. This is because their apex points are not sharp and well defined, which is why a slight displacement of these points may cause considerable error in plotting.
