🔍 Key Concepts

• Basic parts of a sextant and their locations • How the index arm moves and what moves with it • Which parts must stay aligned with the arc and pivot point

💭 Think About

• When you rotate the index arm, which attached part actually changes the observed angle? • Which optical component must swing in an arc exactly centered on the pivot for accurate angle measurement? • Which items are mounted elsewhere on the frame rather than exactly on the pivot?

✅ Before You Answer

• Picture or sketch a sextant and label the index arm pivot point • Identify which part is rigidly attached to the index arm itself • Confirm which parts (like the telescope and horizon glass) are fixed to the frame instead of the moving arm
