In angular measurement, which unit is defined as the subdivision that makes up a degree?

Explanation:
Angles are measured in degrees, but each degree is built from smaller units. A degree contains 60 minutes of arc, and each minute of arc contains 60 seconds of arc. So the subdivision that constitutes a degree is the minute of arc, equal to 1/60 of a degree. A second of arc is even smaller, 1/60 of a minute or 1/3600 of a degree. The radian is a different way to measure angles, and the degree itself isn’t a subdivision.
