Which measurement method utilizes two points of reference?

The triangulation method is a measurement technique that employs two points of reference to determine the position or distance of a point in relation to a coordinate system. This method is commonly used in various fields, such as surveying and navigation, where establishing a precise location or distance is necessary. By using two fixed points, the triangulation method can create a triangle to measure angles and distances accurately, thus allowing for the triangulated calculation of an unknown point's position.

In contrast, the other measurement methods do not specifically rely on two reference points. Scale measurement involves using a calibrated instrument to directly measure an object's dimensions. Absolute measurement refers to the determination of an exact value without reliance on other objects for context, while relative measurement compares the measure of one item to another without creating a triangulated framework for locating an unknown point. Understanding the specifics of the triangulation method enhances clarity when dealing with spatial data and its applications in law enforcement and other relevant fields.
