to the whole, the sectorCGK : for the same reason, the sector KGL is equal to each ofthe sectors BGC, CGK: in the same manner, the sectors EHF,FHM, MHN may be proved equal to one another: therefore,what multiples soever the circumference BL is of the circum-ference BC, the same multiple is the… … sector BGL is equal to the sector EHN ; and if the circumfer-ence BL be greater than EN, the sector BGL is greater thanthe sector EHN ; and if less, less: since, then, there are fourmagnitudes, the two circumferences BC, EF, and the two sec-tors BGC, EHF, and of the circumference BC, and sector…
