You take a bearing of 191° and 313° to two objects. Which bearing of a third object will give the best fix?

🔍 Key Concepts

• Geometry of three-bearing fixes and how the angle between lines of position affects fix quality • Why very small or very large (near 180°) angles between bearings give a poor fix • How to compare the angular separation between each pair of bearings

💭 Think About

• Find the smallest angle between the first two bearings (191° and 313°). Is it acute, right, or obtuse? What does that tell you about the shape of the fix so far? • For each answer choice, compute the angle between that bearing and 191°, and between that bearing and 313°. Which option gives three bearings that are most evenly spaced around the compass? • Which choice avoids any pair of bearings being nearly in line (close to 0° or 180° apart) and avoids a very tiny angle between any two bearings?

✅ Before You Answer

• Calculate and compare the smallest angle between each pair of bearings for all four choices • Look for the option where no angle between any two bearings is very small (sharp) or very large (almost straight) • Check which choice makes the three bearings form a balanced, roughly equal spread around 360°
