VIII. UNITS OF CIRCULAR MEASURE.

483. Angular, or circular measure, is used in estimating latitude and longitude, in measuring the motions of the heavenly bodies, and also in measuring angles.

The circumference of every circle is supposed to be divided into 360 equal parts, called degrees. Each degree is divided into 60 minutes, and each minute into 60 seconds.
