][PROBLEM XII.]
TO DIVIDE A CIRCLE DRAWN IN PERSPECTIVE INTO ANY GIVEN NUMBER OF EQUAL PARTS.
Let A B, [Fig. 32.], be the circle drawn in perspective. It is required to divide it into a given number of equal parts; in this case, 20.
Let K A L be the semicircle used in the construction. Divide the semicircle K A L into half the number of parts required; in this case, 10.
Produce the line E G laterally, as far as may be necessary.
From O, the center of the semicircle K A L, draw radii through the points of division of the semicircle,
