Rectangular coordinates are a system for specifying a point in a two-dimensional space using two measurements that are perpendicular to each other, typically described as being 90 degrees apart. In this context, the correct answer emphasizes the idea that in a Cartesian coordinate system, an object's position is defined by its distance from two axes that intersect at a right angle, serving as the reference points for the measurements.

This system is particularly useful in various fields, including crime scene investigation, because it allows for precise location documentation of evidence and other pertinent items at a scene, facilitating accurate reconstruction and analysis. By using two measurements at right angles, investigators can create a clear and systematic representation of the layout and positioning of various elements within the crime scene.

Other options, although related to measurements, do not accurately capture the definition and application of rectangular coordinates. For instance, straight-line measurements relate more to distance and may not specify the angular relationship, while GPS coordinates involve a different geographic system. Similarly, recalling four corners of a room pertains to boundaries rather than the systematic approach to defining points in a coordinate system.
