Application of Miller's Trisector to the Quinquesection of any Angle "The diagram outlines the Trisector as in the position in which the angle B A L, which may be any angle of less than 225°, is by its aid divided into five equal angles."

The Observatory, vol. 111, no. 1102, p. 134 (1991)] In reference to quinquesect and quinquesection, "Thus a division interval of 5 can be obtained by repeatedly bisecting the angle..." "It is easier to bisect an angle than it is to trisect or quinquesect it."

Food Consumption of Households in Poverty-Stricken Areas of West China: The Case of Shaanxi, Yunnan, and Guizhou "Sample population is classified by using quinquesection: 20% of the poorest populations are taken as poor households, and 20% of secondary poverty-stricken populations are relatively poor households, etc."

London: Royal Society of London, 1809] "Mr. Cavendish describes three methods of quinquesection, which it would be difficult to render intelligible without reference to he figures which accompany his paper; and he also makes an estimate of the comparative accuracy attainable in bisection, trisection, and quinquesection.
