Best Answer

The rigidity of the triangle derives from the fact that you cannot change any angle in a triangle without also changing the length of at least one side; in any other type of polygon, it is possible to alter the angles of the polygon without changing the lengths of the sides. So if you have a physical object in the form of a triangle, the sides are not going to change their length unless you break them. Other shapes can fold up, but triangles won't.

Why is triangle the strongest shape?

It depends on the circumstances. A sphere is the strongest shape for resisting uniform compression from all angles, either when their is a high pressure on the outside or inside (hence the use of dome shaped space suit helmets or dome shaped submarine windows). A triangle is the most rigid shape however, so if you want to cantilever an object, a series of tessellating triangles would provide the strongest structure (hence the widespread use of octet-trusses - the strongest known structure for cantilever stresses). A hexagon is the strongest shape when packed together in a tessellation, but only for compressive forces (hence the ubiquitous hexagonal forms in nature such as the bees honeycombs). The three dimensional equivalent of hexagonal grid is a lorimerlite structure, which is the strongest truss for resisting compressive forces.


Is a square stronger than a rectangle?

yes because they are more compact and balanced. The strongest shape is a triangle, so putting two obtuse triangles together to form a square is how most structures are created to be stable.
