What technique is used to create a network of triangles for determining unknown distances?

• A. Trilateration
• B. Triangulation
• C. Interpolation
• D. Georeferencing

Answer: (B)

The technique used to create a network of triangles for determining unknown distances is triangulation. This method involves measuring angles from known points, which then allows for the calculation of distances based on the geometric properties of triangles. In triangulation, the positions of known points form the vertices of the triangles. By measuring the angles between these known points and an unknown point, one can use trigonometric principles to determine the distance to that unknown point. This is particularly useful in surveying and navigation applications where precise measurements are vital. The other techniques mentioned serve different purposes. Trilateration, for instance, is focused on measuring distances using circles rather than angles, while interpolation involves estimating unknown values between known data points. Georeferencing is a method used for aligning spatial data with geographical coordinates, rather than directly measuring distances through triangulation. This distinction highlights why triangulation is the appropriate choice for determining unknown distances through a network of triangles.
