What is the baseline measuring method used to locate a spot using reference lines that measure the shortest distance at right angles?

• A. Triangulation
• B. Coordinate (Baseline)
• C. Polar Coordinates
• D. Rectilinear Projection

Answer: (B)

The essential idea is locating a point by its perpendicular offsets from reference lines, described as coordinates tied to a baseline. You set a baseline as one axis and often use a second line perpendicular to it to form an orthogonal grid. The spot is determined by two shortest distances: how far along the baseline it is, and how far away from the baseline it sits. Measuring those perpendicular distances gives you the coordinates that pinpoint the location precisely. This approach differs from methods that rely on angles from known points (triangulation) or on a single reference point with distance and direction (polar coordinates). It also isn’t about projecting along lines in a rectilinear way without using a coordinate grid. By using perpendicular measurements to reference lines, you get a straightforward, unambiguous location on a defined baseline grid.
