Non ſecus ſi ab eadem asymptoto A C educantur quatuor rectæ lineæ inter ſe
æquidiſtantes F I, G K, H L, C E, quarum duæ priores F I, G K, centro pro-
pinquiores ſint, quando omnes infra centrum A collocantur; vel magis à centro
recedant, quando omnes in productione A Z exiſtunt; aut certe duæ F I, G K
ſupra centrum, & H L, C E infra centrum exiſtant: Tunc ſimiliter in quoli-
bet caſu dicentur rectæ lineæ F I, G K vlterius tendere ad partes centri, &
asympoti A B, quàm duæ aliæ H L, C E.

Si in vna aſymptoto A C, hyperboles D E ſumantur duo ſegmenta
æqualia F G, H C, & à punctis diuiſionum ducantur quatuor rectæ
lineæ F I, G K, H L, C E parallelæ inter ſe, vſque ad hyperbolen:
Dico quod differentia duarum æquidiſtantium F I, G K ad partes cen-
tri, & alterius aſymptoti A B vlterius tendentium, maior erit differen-
tia reliquarum H L, C E.
