8547Conicor. Lib. V. figuræ compoſitæ, vel diuiſæ, & c. Quia E K ad K D, atque C F ad F D eandem
proportionem habebant, quàm latus tranſuerſum ad rectum; ergo componendo in
hyperbola, & diuidendo in ellipſi erit E D ad D K, vt C D ad D F.
Et ponamus re-
11h62[Figure 62] ctangulum F G cõ-
mune, & c. Scilicet
rectangulũ F G ad-
datur in hyperbola,
& auferatur cõmu-
niter in ellipſi.
Et propterea E
22i K ad B G, nempe
K R ad R G, & c.
Quia propter ſimili-
tudinem triangulo-
rum E K R, & B G
R erit E K ad B G,
vt K R ad R G; qua-
re K R ad R G maio-
rem proportionẽ ha-
bet, quàm G M ad
M K; & componen-
do K G ad G R ma-
iorem rationem ha-
bet, quam eadem G
K ad K M, quare
K M, nẽpe e i æqua-
lis D F maior eſt,
quàm G R.
Et auferẽdo ho-
33k mologũ ab homo-
logo in hyperbola,
& coniungendo e
a in ellipſi, habebit, & c. Scilicet comparando homologorum differentias in hy-
44Lem. 4.
præmiſ. perbola, eorundem ſummas in ellipſi, ideſt C T ad B O, nempe C H ad H O (pro-
pter ſimilitudinem triangulorum C H T, & O H B) habebit maiorem proportionem,
quàm I C ad C S, nempe C D ad D F.
Poſtea educamus ex E lineam occurrentem ſectioni in V, & c. Educamus
55l ex E lineam occurrentem ſectioni in V, quæ ſecet axim in Z, & S M in Y.
Et per f producamus f g h parallelam axi A D, & c. Et per f ducamus f g pa-
66m rallelam axi A D, quæ ſecet tangentem B a in h, & L F in g, atque V c ſecet illam in
i, & S M in e.
Et ponamus rectangulum F f communiter, & c. Et communiter addamus in
77n hyperbola, & auferamus in ellipſi rectangulum F f, fiet rectangulum B fg æquale
rectangulo g F C. Nomina Inuerſi, & Trutinatæ definita fuerunt in primo libro ab
interprete Arabico.
