hey mate check 17 ............
2 triangles lo pehla. that is DEC and BEF. usma ASA congruency hae dekho solution mae. eslia side kaa ratio same hoga.par hamara pas CE = BE hae eslia ratio CE/BE = 1 ho jayaga, matlab dono equal ho jayaga.hama pata hae ki parallelogram mae opp sides equal hoti hae, hamara pas ratio vala mae solution mae dekho DC=FB hae Dc side hae parallelogram ki tho Ab ka equal hoga .opp side equal hoti hae parallelogram ki . thoDC= AB and DC = FB eslia AB = FB
