Introduction of Arches reduces the bending moment at cross sections due to presence of horizontal force at the support whenever bridge is loaded and thus requirement of cross section is lesser. When triangles are easy to propagate and can have tension/compression only if used as 2-point member in bridges (forces acts only the end of any member not in between), Due to absence of bending moment it also reduces the cross-section requirement. Therefore, if we introduce arches and triangles cross section requirements of each small member get reduced.

Why are triangles used in the design of structures such as bridges?
so the bridge cant fall down when the cars are on it. And the triagles can keep i
How is the ford circle used?
ford circle can be used for bridge making
What can isosceles triangles be used in?
Isosceles triangles can be used in domes
What geometric shapes are used to make bridges strong?
Triangles are used extensively because they are fundamentally rigid, because three line segments can define one and only one triangle. Compare a trianlge to, say, a square, which could flex at its vertices to form a rhombus. If you take a square, however, and insert one diagonal, you basically have two triangles, which make the square rigid and not prone to collapse. Arches are also fundamental in architecture because of the way they distribute weight to the pillars that support them. Arches also convert horizontal and lateral forces to vertical ones.
Can Pythagorean Theorem be used on all types of triangles?
No it can only be used with right angle triangles.
