Triangles are used to make bridges because a triangle is an undeformable shape, as considered
in the civil engineering field, it can hold the most force when applied to it, compared to
quadrilaterals and arches. Isosceles triangles were used to construct a bridge in which the base
(unequal side) of an isosceles triangle is 4 m and its perimeter is 20 m.

Answer:
Triangles are used in bridges because they evenly distribute weight without changing their proportions. When force is applied on a shape like a rectangle it would flatten out. Before triangles were used in bridges, they were weak and could not be very big.
