A triangle in which an angle of the triangle is less than 30° or greater than 120° is known as ill conditioned triangle. Equilateral Triangle is the best-suited triangle in Chain Triangulation or Chain Surveying.

What do you mean by well conditioned and ill conditioned triangle?

A well conditioned triangle has angle not less than 30 and not more than 120 respectively. Jka said: (Jul 5, 2020) Well conditioned triangle:all angles >30 & <120. Ill conditioned triangle: any one angle <30 or >120.

What is the principle of triangulation?

In surveying, triangulation is the process of determining the location of a point by measuring only angles to it from known points at either end of a fixed baseline, rather than measuring distances to the point directly as in trilateration.
