Answer:
triangle inequality
Civil Engineers use the triangle inequality theorem frequently because the area that they work in deals with transportation, urban planning, and surveying. These specific fields use triangle inequalities frequently to efficiently complete the task assigned. By using the Triangle Inequality Theorem, an engineer can find a reasonable range of values for any unknown distance. This can be extremely beneficial when trying to find a rough estimate of the amount of material needed to build a structure with undetermined lengths. It makes estimates more accurate, and engineers can plan better according to it. For example, the engineers who designed the statue below used the Triangle Inequality Theorem to determine the unknown lengths and also create a rough estimate of the amount of steel needed.
