The triangle is the strongest geometric shape. Triangles are very hard to distort from their normal shape because of their fixed angles and ability to distribute force evenly to the other sides. This force is then transferred to adjacent triangles.
A triangle is often paired with a dome to create a very solid structure. The domes that incorporate the use of triangles in their structure are referred to as geodesic domes. These domes distribute pressure in a cascading pattern to dissipate stress without causing structural damage. Many other geometric figures can be broken down into triangles. These figures include squares, pentagons and hexagons.
