What is the term for the units that make up each degree?

The correct answer is minutes, which are the units that subdivide degrees in the measurement of angles. Each degree is divided into 60 minutes, which allow for precise measurements in navigation and mapping, particularly in aviation where accurate positioning is crucial. This division allows for fine adjustments and is essential for tasks like plotting courses and providing accurate location information on charts.

While degrees are the primary unit of angular measurement, seconds are a smaller subdivision of minutes, with each minute divided into 60 seconds. However, since the question asks specifically for the unit that directly makes up each degree, minutes is the most accurate response.

Hours relate to time rather than angular measurement, and parts are not standard terms used in this context. Understanding this hierarchy of measurement units is key for anyone involved in navigation within the National Airspace System.
