The selfe same also followeth in parallelogrames.* 1.1 For if vpon the base AB be set on one & the same side these equal parallelogrames ABCD & ABGE, they shall of necessitie be in the selfe same parallel lines. For if not, but one of them is

B being equall to the parallelograme ABCD be set within the same parallel lines: wherefore the same parallelograme BF beyng e∣quall to the parallelograme ABCD (by the 35. proposition) shall also be equall to the other pa∣rallelograme ABGE (by the first common sen∣tence) For the parallelograme ABGE is by sup∣position equall to the parallelogramme ABCD: whefore the parallelograme BF being equall to the parallelograme ABGE, the parte shall bee e∣qual to the whole, which is absurde. The same in∣conuenience also will followe, if it fall without. VVherefore it can neither fall within nor with∣out. VVherfore equall parallelogrames beyng vpon one and the selfe same base and on one and the same side, are also in the selfe same parallel lines.
