Another Method, still nearei% 



Divide the diameter A B into 

 as many equal parts as the figure 

 has sides, as before. From the 

 centre o rJiise the perpendicular 

 ow, which produce till m n be 

 three-fourths of the radius o in, 

 T'rom n draw n C through the 

 second division of the diameter, 

 and the line AC will be the side 

 of the polygon still nearer than 

 before ; or the arc A C, one of 

 the equal parts, into which the 

 divided.

About a given Circle to circumscrihe any Polygon* 



Find the points my «, /, Sec. as in 

 the last problem, to which draw 

 radii ;«o, rjo, &c. to the centre of 

 the circle. Then through these 

 points my ;;, &c. and perpendicular 

 to these radii, draw the sides of the 

 polygon.
