gre I,8Ἐὰν ἄρα δύο τρίγωνα τὰς δύο πλευρὰς [ταῖς] δύο πλευραῖς ἴσας ἔχῃ ἑκατέραν ἑκατέρᾳ καὶ τὴν βάσιν τῇ βάσει ἴσην ἔχῃ, καὶ τὴν γωνίαν τῇ γωνίᾳ ἴσην ἕξει τὴν ὑπὸ τῶν ἴσων εὐθειῶν περιεχομένην:
lat GerardCum ergo duo latera unius trianguli duobus lateribus alterius trianguli equantur, quodque suo relativo, et basis basi equalis existit, tunc duo anguli duobus lateribus equalibus utriusque trianguli comprehensi sunt equales.
1. This proposition wishes to prove that the angles which are contained by the equal straight lines will be equal. Even though these angles are mentioned in the original statement at the beginning, it is not followed up in the Tuṣi version, and the original idea seems lost throughout and at the end.
ara Nairizi p. 66فكل مثلثين تساوى ضلعان من احدهما ضلعين من الاخر كل ضلع لنظير وتساوى القاعدة القاعدة فان الزاويتين اللتين يحيط بهما الاضلاع المتساوية متساويتان
san 15,5–7tasmāt tribhujaṃ tribhu(6)jopari sthāsyaty eva | koṇā api (7) koṇasamānā bhavanty eva |
lat ClaviusQuare si duo triangula duo latera habuerint duobus lateribus, &c.
