Si a punctis, F, 6, demittantur ad planum
horologii duo perpendiculareo FH, 6T, ipsum
tangenteo in punetis, H, T, quae connectantur
recta HT, et duo remotiora umbac puncta
C, F., connectantur itiam aecta, CF; Duo
rectas, HT, CF, utaimque produitao, vie
concurrere in aliquo puncto, vel esse
parallelat.
Cum enim duae acctae HT, CF, sint in
aodem plano, nempe in plane horologi;
propositio manfesta est ex definitione
parallelarum.
Propoor. 6.
Si aecto tIT, CF, parallalae sunt, recta
F6, ipois quoque parallela eot.
Nam cum utraque recta FH, 6I, perpen
dicularis dueta sit ad planum horologis;
erunt igitus FH, GF parallalo, ac proinde
rectae ipsarum entrema connactentes FC, HI
in eodem cum ipois peano. Rursuo cum
rectae F6, CF, sint in plano triangue ACF,
sunt ergo ipsae quoque in uno peano.Stem
recte HII, CF, sunt etiam, in uno plano.
habemus itaque tuia plana se mutuo sacantia
F6HF, FGCF, HICF, quorum cum duoe
mccosectioneo HF, CF. ponantur Ca
C90 e
reliqua comunis soctio F6 ipuis quoque
