What is the method called where measurements are made from two or more fixed points to intersect at the location of an object?

The method where measurements are made from two or more fixed points to pinpoint the location of an object is known as triangulation. This technique utilizes the principle of geometry, specifically the formation of triangles. By measuring the angles or distances from known points to the unknown point, investigators can calculate the exact position using the properties of triangles. Triangulation is frequently employed in various fields, including surveying, navigation, and investigations, due to its accuracy and reliability. It is particularly useful in crime scene investigations where precise location information can aid in recreating events and determining evidence placement.

The other methodologies mentioned, such as rectangulation, projection, and schematic methods, do not pertain to the geometric principles that define the triangulation process. These methods either focus on different techniques of representation or measurement that lack the triangulation's foundational reliance on forming triangles for accurate location determination.
