ne (3. def. 11.); thereforeeach of the angles ABD, ABE is a right angle; and because thestraight line BD meets the parallel straight lines AB, CD, theangles ABD,CDB are together equal (29. 1.) to two right angles:and ABD is a right angle; therefore also CDB is a right angle,and CD perpendicular to… … D them is a right angle; therefore the base C AD is equal (4. 1.) to the base BE: again,because AB is equal to DE, and EB toAD; the two AB, BE are equal to the twoED, DA; and the base AE is common tothe triangles ABE, EDA; wherefore theangle ABE is equal (8. 1.) to the angleEDA, and ABE is a right…
