It is shown that the most advantageous form of a triangle in which three sides are measured is an isosceles triangle whose equal angles are 52 ° 46 '. Exactly the same triangle is advantageous, as we know, in triangulation. They can be used in practice, when you need to transfer the length or the control angle only once. In solid networks of triangulation such triangles are not profitable.
