the same straight linesin the plane opposite to the base, are equal to oneanother. Let the parallelepipeds CM, CN be upon the same base AB,and of the same altitude, but their insisting straight lines AF,AG, LM, LN, CD, CE, BH, BK not terminated in the samestraight lines: the solids CM, CN are equal… … and that the plane LBHM is that in which are the parallels LB,MHPQ, in which also is the figure BLPQ ; and the plane ACDFis that in which are the parallels AC, FDOR, in which also isthe figure C AOR; therefore the figures BLPQ, C AOR are inparallel planes: in like manner, because the plane ALNG is…
