#### Transcript of HOW ARE TRIANGLES USED IN THE REAL WORLD

How triangles are related to geometry and society: "Applications of Geometry"
If there is a single most important shape in engineering, it is the triangle.
Unlike a rectangle, a triangle cannot be deformed without changing the length of one of its sides or breaking one of its joints. In fact, one of the simplest ways to strengthen a rectangle is to add supports that form triangles at the rectangle's corners or across its diagonal length. A single support between two diagonal corners greatly strengthens a rectangle by turning it into two triangles. Triangulation of material, adds strength by eliminating lateral movement.
Where is Geometry used?
Why is Geometry important to society?
