Walking around, you might notice the sheer number of triangles in modern structures. Many roofs are triangles. Many supports are triangles. Why is this? One reason is that the triangle is a simple, yet efficient shape. Another is that triangles provide excellent structural strength. As the Cleaning Technology Group explains, “The triangle is the only two dimensional polygon that, if constructed of rigid members with hinged corners, is absolutely fixed in shape up to the compressive and tensile limits of its members.  A square, for example, can easily be mis-shapen into a parallelogram.” Thus, the triangle’s simplicity, along with its structural benefits, makes it a go-to choice in modern architecture.
