Triangulation – מילון אנגלי-אנגלי
triangulation
n.
use of triangles for surveying or measuring
Triangulation
In
trigonometry and
geometry,
triangulation is the process of determining the location of a point by measuring
angles to it from known points at either end of a fixed baseline, rather than measuring distances to the point directly (
trilateration). The point can then be fixed as the third point of a triangle with one known side and two known angles.
triangulation
Noun
1. a trigonometric method of determining the position of a fixed point from the angles to it from two fixed points a known distance apart; useful in navigation
(hypernym) trigonometry, trig
(derivation) triangulate
2. a method of surveying; the area is divided into triangles and the length of one side and its angles with the other two are measured, then the lengths of the other sides can be calculated
(hypernym) surveying
(derivation) triangulate
Triangulation (die)
nf.
triangulation, use of triangles for surveying or measuring
Triangulation
(n.)
The series or network of triangles into which the face of a country, or any portion of it, is divided in a trigonometrical survey; the operation of measuring the elements necessary to determine the triangles into which the country to be surveyed is supposed to be divided, and thus to fix the positions and distances of the several points connected by them.
