342330 AB, maius ſit latere AC, erit & angulus C, angulo B, maior. Quare B, acu-
1119. primi.187[Figure 187] tus erit.
Nam ſi rectus eſſet, aut maior, eſſet C, etiam
maior recto.
quod eſt abſurdum; quòd B, C, ſint mino-

Cum ergo & A, ponatur acutus, ca-
det perpendicularis CD, intra triangulum.

Et quia, vt in tractatu tangentium oſtendimus, poſito ſinu toto BD, recta
