Question: 1 / 400

What defines indirect measurements?

Measurements using standard tape measures

Measurements made via satellite positioning

Measurements inferred when direct measurement is impractical

Indirect measurements refer to methods of obtaining measurements when direct measurement is not feasible or practical. This approach includes techniques that rely on calculating distances or dimensions based on known relationships between other measurable quantities or using methods such as triangulation, trigonometry, or other derived calculations.

For example, if a surveyor cannot directly measure the height of a building due to safety concerns or obstacles, they might measure the distance from the building and the angle of elevation to calculate the height indirectly. This method is critical in situations where direct access is restricted or measurements are too dangerous or difficult to obtain.

In contrast, methods that involve standard tape measures, satellite positioning, or solely visual references pertain to direct measurement or specific technologies rather than the concept of inferring measures when direct methods are impractical.
