Investigators may use either imaginary triangles or rectangles to record the position of an evidence item. 5). By placing an evidence item at the corner of a rectangle and knowing the lengths of the two sides that meet at that corner, an investigator can precisely re-create its location. Accurately determining an object’s position within a triangle requires the length of one side and the two angles formed by lines leading from either end of that imaginary line to the object. For example, if we know that the distance between two reference markers is 10 ft and the angle of a line drawn from the evidence item to one reference marker is 34° and the angle of a line drawn from the evidence item to the other reference marker is 80°, we can draw lines having the proper angle from each end of the measured line until those two lines intersect.
