1.22.2. Principle of triangulation

Try these first

1. 1.

   Define triangulation in your own words.

   Hint

   Think about how triangles are used in measurements.

2. 2.

   What is a triangulation station?

   Hint

   Consider where measurements are taken from in a triangle.

3. 3.

   What is triangulation primarily used for?

   • Mapping
   • Cooking
   • Sports
   • Gaming

   Hint

   Think about areas where exact measurements are crucial.

4. 4.

   True or False: The shape of triangles does not affect surveying accuracy.

   • True
   • False

   Hint

   Consider the relationship between triangle shapes and measurement precision.

5. 5.

   Design a triangulation scheme for a proposed large civil engineering project. Discuss what factors you would consider for site selection.

   Hint

   List environmental and logistical considerations for accessibility and accuracy.

6. 6.

   If triangulation is performed but the angles calculated are consistently off by 2 degrees, analyze how this would affect the overall accuracy of the survey.

   Hint

   Evaluate the mathematical relationships within triangle geometry.
