In a triangulation net, the strongest route has which characteristic?

• A. S
• B. R
• C. Q
• D. T

Answer: (B)

In a triangulation net, strength comes from how well a route is constrained by many independent triangles. The strongest route is the one that traverses the most triangles along the path, providing the greatest redundancy of angular observations. More triangles mean more constraints on the positions of the stations along that route, so random errors in individual measurements have less overall effect and the line becomes more stable and reliable. Good angular geometry along the route (angles not too small or obtuse) keeps the geometry well-conditioned, further reducing error amplification. Therefore, the route with the maximum number of triangles and favorable geometry is the strongest. The other options describe properties that don’t deliver the same level of constraint and stability.
