Measurement of Circles (chapter)

Abstract
The measurement of circles is closely connected to the measurement of angles. This is because the measurement has a rotational aspect; that is, one ray must be turned about the vertex until it coincides with a more static aspect. The circle is the perfect tool for measuring planes of angles, because any angle cuts off the same fractional part of every circle whose center is at the vertex of the angle.
This chapter discusses the methods measuring circles.
