Which sketch method measures the distance of objects from fixed points such as walls or windows?

• A. Coordinate method
• B. Triangulation method
• C. Cross projection method
• D. Perspective method

Answer: (A)

Measuring an object's position using fixed features creates a coordinate-based layout. By anchoring reference lines to walls or windows and recording how far the object is from each line, you assign it precise x and y coordinates on a grid. This directly captures the distances from those fixed points, which is exactly what the method described seeks. The other approaches rely on different ideas: triangulation uses angles from known points to locate a position rather than measuring distances to fixed features; cross projection uses projections onto reference lines to infer location, which emphasizes alignment over direct offset from fixed points; perspective draws recreate scenes from a chosen eye point, focusing on depth and vanishing points rather than fixed-point distances. Because the prompt calls for measuring distance from fixed references, the coordinate method fits best.
