In the method where objects are located using two perpendicular lines, what is this method called?

• A. Triangulation
• B. Rectangulation
• C. Legend
• D. Close-Up Photography

Answer: (B)

The process relies on creating a rectangular grid by using two lines that meet at a right angle. By projecting or measuring along each perpendicular line from a known reference, you locate the object at the intersection of the two lines. This coordinate-based approach is known as rectangulation. For example, from a known origin you would go a certain distance along one line and a certain distance along the perpendicular line; where those two lines cross is the object's position. This differs from triangulation, which uses angles from known points to determine a location, and from options like a map legend or close-up photography, which don’t describe locating a point with perpendicular directions.
