"도 (Degree)" refers to a unit of measurement used to quantify angles and temperature. In geometry, a full circle is divided into 360 degrees, with each degree representing a specific angle. This system helps in various fields, including mathematics, engineering, and navigation. In terms of temperature, degrees are used to express heat levels. The two most common scales are Celsius and Fahrenheit. In the Celsius scale, water freezes at 0 degrees and boils at 100 degrees, while in the Fahrenheit scale, these points are 32 degrees and 212 degrees, respectively.
