Which plotting method uses a baseline to locate evidence?

• A. Triangulation
• B. Rectangular Coordinates
• C. Baseline
• D. Polar Coordinates

Answer: (C)

Plotting evidence with a baseline means using a long straight reference line as the anchor for measurements. For each item, you measure how far away it lies from that baseline (the perpendicular distance) and also note where along the baseline that perpendicular from the item would start. Putting those two pieces together gives the location of the item on the map. This approach works well when you have a clear straight reference line in the scene and want a simple, scalable way to map positions. Triangulation would use two fixed points and distances to those points to pinpoint a location, which isn’t about a single baseline. Rectangular coordinates rely on two perpendicular axes to assign X and Y coordinates, not a single baseline reference. Polar coordinates use a single reference point with an angle and distance, not a baseline line.
