Final answer:
The statement is true; a circle is divided into 360 degrees, which is essential for measuring angles and celestial positions with high precision in fields like geometry and astronomy.
Step-by-step explanation:
The statement that a circle is divided into 360 equal parts, called degrees, is True. The degree is a unit of measurement used to quantify angles and rotations. One full circle equates to 360 degrees. This division allows for precise measurements in various fields, including geometry, astronomy, and navigation. When we discuss Angles in the Sky, we often reference this system of degrees, minutes, and seconds to measure the position of celestial objects.
In addition to degrees, each degree is further divided into 60 minutes of arc (also known as arc minutes), and each minute is subdivided into 60 seconds of arc (arc seconds). This system is especially important in astronomy where precision is crucial, as the observed parallaxes of stars are extremely fine and can be less than one arc second.
Understanding how a circle is divided into degrees helps with grasping basic concepts of geometry as well as more advanced applications such as calculating distances on the Earth's surface using lines of latitude and longitude. Each degree on the Earth's surface represents a specific location in the graticule system, allowing geographers to determine exact positions for study and mapping.
