DE CENTRO GRAVIT. SOLID.
æquidiſtant autem c g o, m n p. ergo parallelogrãma ſunt
o n, g m, &
linea m n æqualis c g; & n p ipſi g o. aptatis igi-
tur K l m, a b c triãgulis, quæ æqualia &
ſimilia sũt; linea m p
in c o, &
punctum n in g cadet. Quòd cũ g ſit centrum gra-
uitatis trianguli a b c, &
n trianguli K l m grauitatis cen-
trum erit id, quod demonſtrandum relinquebatur.
Simili
ratione idem contingere demonſtrabimus in aliis priſma-
tibus, ſiue quadrilatera, ſiue plurilatera habeant plana,
quæ opponuntur.

COROLLARIVM.

Exiam demonſtratis perſpicue apparet, cuius
Iibet priſmatis axem, parallelogrammorum lat eri
bus, quæ ab oppoſitis planis ducũtur æquidiſtare.

THEOREMA VI. PROPOSITIO VI.

Cuiuslibet priſmatis centrum grauitatis eſt in
plano, quod oppoſitis planis æquidiſtans, reli-
quorum planorum latera bifariam diuidit.

gula a c e, b d f:
