Lineae rectae de latera quaelibet
similia sunt.  (seu nec concavum et
convexum in ea discerni non potest) quia
de duobis tantum soh ex duo extrema
ad eam determinandam sufficiunt
quil ab extremis autem solis nulla ratio
poti potest, cur hoc latr latus huc alterum
illuc potius respiciat.
Duae rectae concurrentes productae
sese secaburit. Htoc demonstrari non
potest nisi phius consideratio plani prae-
desselit. Considerandum enim duas rectas
puunctum commune habentes esse in eodem
plano rectaque in plano, producta,
partem punc in definita existente
partem punctorum e aliam qum partem
plan ab hac alteram ab altera rectae
parte esse. Et rectam quoe ad
alteram accedit, continuo ad pltatus
alteram epartem accedere uniformiter
adeoque necessario ad eam pervenore.
Angulus rectianens est id quod
in duatum rectarum siconcursu con-
siderari potest, nulla longitudinis rectarum
ratione habita. Seu id quod idem
manet duabus rectis usque ad commune
punctum productis longitudine ipsarum
rectarum utcunque mutata.

A Antgulus rectas est in recta
cum ad rectam utcunque productam usque
producitur recta, et punc duo anguli
quos f qui orcuntua, qui eo ipso
oriuntur (quos vocant deinceps)
sunt aequales: uterque  llicitur rectus

Duo anguli recti sunt aequales
inter se.
Anguli autem alter altero major intelligitur,
Cum partem habet alteri aequalem sed
video tamen difficultatem, quomodo
enim angulus uni alterius pars est
seu quomodo angulas HBG pars est ansuli
ABC hoc enim ex neque enim linca e
lineae HB, BG linearum AB. BC. sunt partes.
quod sidicas ansulum esse id quod liatis.
linearum longitudine utcunque mulata idem
nanet non. ideo intelligitur aut esse
tale aliquid aut partes habere
