Examples of triangulation are seen all around us especially in the construction industry (building and civil engineering). Folding a simple art straw into a triangular shape and then attempting to break it gives us some idea of the strength of triangulation. This is why it is popular for building structures from large to small, permanent to temporary.
A triangular form is one of the strongest shapes known to man. It is not surprising then that ‘triangulation’ is used in the construction of buildings and structures.
Some examples are shown below. Look carefully how numerous triangles make each structure.

QUESTIONS:
1. Collect a number or photographs/diagrams of structures that rely on ‘triangulation’ for their strength, for example a famous bridge. For each structure explain how triangulation is used.
