_C_Ontineri autem parallelepipedum voco ſub tribus rectis eiuſdem
angulum ſolidum continentibus, quarum dua qualibet rectum
angulum conſtituunt, ſiue ſub earum quauis, & parallelogrammo re-
ctangulo ſub reliquis duabus; ita vt, cum dico parallelepipedum ſub
tali recta linea, & tali rectangulo, ſiue ſub talibus tribus rectis lineis,
intelligam illud parallelepipedum habere angulum ſolidum rectis an-
gulis conſtitutum, veluti in iſtis Theorematibus ipſum aſſumo, igitur
patet nos ex tribus rectis parallelepipedum continentibus quamlibet
poſſe pro altitudine ſumere, & rectangulum ſub reliquis duabus pro
baſi.
