The symbol ° is used to denote which measurement unit?

• A. Minute
• B. Second
• C. Degree
• D. Radian

Answer: (C)

The symbol ° denotes degrees, an angular unit. One degree is 1/360 of a full circle, and larger angles are described using this unit. For finer angular measurements, arcminutes and arcseconds are used, shown with the symbols ′ and ″, dividing a degree into 60 minutes and each minute into 60 seconds. Radians are another angular unit, usually abbreviated rad and not written with a degree symbol. While ° can appear after numbers to indicate temperature (degrees Celsius or Fahrenheit), in this context it represents angular degrees.
