The map symbol for a fire hydrant is what shape?

• A. Solid circle
• B. Triangle
• C. Square
• D. Diamond

Answer: (A)

Map symbols are designed to be quickly recognizable by looking at a simple shape. A fire hydrant is a precise, fixed point where water is available, so the symbol chosen is a small, solid circle. The circle reads clearly at various map scales and against different backgrounds, making hydrant locations easy to spot during planning and response. Shapes like triangles, squares, or diamonds are typically reserved for other features or warnings, so using a circle helps prevent confusion and keeps hydrants distinct from those other symbols. Color often adds another layer (like blue for water), but the shape alone is what ensures hydrants stand out as known, fixed water sources on the map.
