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-

& auferatur cõmu-

Et propterea E

K R ad R G, & c.
Quia propter ſimili-
tudinem triangulo-

vt K R ad R G; qua-
re K R ad R G maio-

quàm I C ad C S, nempe C D ad D F.

Poſtea educamus ex E lineam occurrentem ſectioni in V, & c. Educamus

Et ponamus rectangulum F f communiter, & c. Et communiter addamus in
