Constructio in casu priore evadet paulo simplicior jungendo BP, & in ea si opus est producta, capiendo Bp ad BP ut est PR ad PT, & per p agendo rectam insinitam pD ipsi SPT pa∣rallelam, in{que} ea capiendo semper pD aequalem Pr, & agendo rectas BD, Cr concurrentes in d. Nam cum sint Pr ad Pt, PR ad PT, pB ad PB, pD ad Pt in eadem ratione, erunt pD & Pr semper aequales.
