🔍 Key Concepts

• Radar range as a distance measurement from a known, fixed object • The geometric shape formed by all points at the same distance from one fixed point • Difference between a bearing line and a range line on a chart

💭 Think About

• If your radar shows you are 6 miles from a lighthouse, what does that tell you about all the possible places your vessel could be on the chart? • Think about what shape is formed on a chart by all points that are exactly the same distance from a single point on the coast. • Which of the choices matches the locus of points that are a constant distance from one fixed coastal object?

✅ Before You Answer

• Confirm that range is a distance, not a direction. • Visualize or sketch the locus of points at constant distance from the coastal object. • Eliminate any option that describes a straight line, direction, or parallel feature rather than a constant-distance shape.
