Answer» $i)BE \:is \:<klux>TRANSVERSAL</klux> \: to \: AB \:and \: EF$ $\angle {ABE} = \angle {BEF} = 70\degree$ /* ALTERNATE angles are EQUAL / $\therefore AB \parallel EF \: --(1)$ $ii)CE \:is \:Transversal \: to \: CD \:and \: EF$ $\angle {DCE} + \angle {CEF}$ $= 140\degree + 40 \degree$ $= 180\degree$ / Sum of interior angles same SIDE of the the Transversal is supplementary / $\therefore EF \parallel CD \: --(2)$ / From (1) and (2) / $AB \parallel EF \: and \: EF \parallel CD$ $\implies AB \parallel CD$ / Transitive Property */ •••♪
