equal Parts, not exceeding ten. 
Practice. By the preceding defcribe the Circle afcg 5 
draw the Diameter aec, and "twill divide the Czrc/e into two 
equal Parts; make ¢dand ad equal to ae, and draw 6d, which 
will divide the Circle into three equal Parts ; draw fg-at Right 
Angles to ac, and join f4, which is the fourth Divifion , on

§ 1O divide the Gircumference of any Circle into 360 equal 
Parts, or Degrees. cal 
DeriniTion. A Degree is the three hundred and ‘ixtieth 
Part of the Circumference of any Circle, (be it great or fmall,) 
each of thofe Degrees are divided into fixty equat Parts, hed } 
led Minutes; and» each of thofe into /xty Parts more, called 
Seconds; and fo to Thirds, Fourths, ce. > But: fach Subdi- 
vifions has no Place herein, any further than Minutes. 
Practice.: Deferibe the Circle a che, diaw the two Dias 
meters aband ec at Right Angles, and the Circle will be di- 
vided into four equal Parts; make 4g, 4%, each equal to a d,
