🔍 Key Concepts

• A full circle of direction is traditionally divided into a certain number of degrees • Think about how headings like North, East, South, and West are expressed on a compass (e.g., 090°, 180°) • The relationship between quadrants (NE, SE, SW, NW) and total degrees on a compass card

💭 Think About

• If one right angle is 90°, how many right angles fit into a full circle? • When a ship’s heading changes from due North to due East to due South and so on, what are the usual degree values used in navigation? • Which of the answer choices matches the standard degree system used in most charts and navigational problems?

✅ Before You Answer

• Confirm how many degrees are in a full circle in basic geometry • Check which answer choice is commonly used for compass headings in navigation problems • Make sure you are not confusing grads or mils (other angle units) with the standard degree system used on most maritime compass cards
