Why are girders so often arranged to form triangles in the construction of bridges and other structures? and How do Engineers decide to subdivide into smaller triangles? In what condition this arrangement fails? If vertical post is taken out, what type of failure will it undergo?

The answer by Ben Reimers more or less answers your question. Though I would like to add one more point and explain it to you from point of view of engineering mechanics.In a given arrangement of girders each side of the polygon is identified as a link in engineering terminology.The degree's of freedom of a linkage is given by the formula:F= 3(n-1) - 2lwhere,F= degree's of freedom of an arrangementn= number of linksl= no of pairsFor more information on degree's of freedom visit: Chapter 4. Basic Kinematics of Constrained Rigid BodiesUsing this formula we find that for-triangle, F= 0rectangle, F= 1pentagon, F= 2and so on..*in the above figure m= degree's of freedomThis means that the links of a triangle can not move under application of a force while links of other shapes like rectangle, pentagon, hexagon etc can easily move/rotate/deform about its joints. (That is common sense, isn't it? ) Thus a rectangle can be deformed about its joints under the application of a force where as a triangle cannot. That's why a rectangular linkage is called a mechanism (one which moves) and a triangular linkage is called a structure (one which can not move)The strength of a triangular arrangement depends on the strength of the material used in the links and its thickness. There is no inherent weakness in the triangular arrangement.In case of other polygons (rectangle, pentagon, etc) the degree of freedom is greater than zero hence they are inherently weak about their joints.
