An investigator making a rough sketch of a crime scene. Being outdoors makes his task more challenging. He uses fixed objects, such as a shed, a fence, and a few trees as reference points from which he will measure the distance between them and the body of the victims. When finished, Rich's sketch provides viewers with a bird's-eye view of the crime scene. What sketching method is he using? A) baseline B) cross-projection method C) coordinate method D) triangulation method

D) triangulation method

The investigator is using the triangulation method. This method involves using fixed points of reference to measure distances and angles, creating a three-dimensional representation of the crime scene. It is particularly useful for outdoor scenes where fixed points are available.
