...within the circumference. The circumference of every circle is usually supposed to be divided into 860 **equal parts, called DEGREES ; each degree into 60 equal parts, called MINUTES ; each** minute into 60 equal parts, called SECONDS ; and so on. Degrees, minutes, and seconds, are thus expressed,... | |
