If ∆ABC <span lan

Answer :

We know that, sides of one triangle are proportional to the side of the other triangle, and then their corresponding angles are also equal, so by SSS similarity, triangles are similar.

∆ABC EDF


AB/ED = BC/DF = AC/EF


(By similarity property)



Taking first two terms, we get


AB/ED = BC/DF


AB.DF = ED.BC


So, option (d) is true


Taking last two terms, we get


BC/DF = AC/EF


BC.EF = AC.DF


So, option (A) is true


Taking first and last terms, we get,


AB/ED = AC/EF


AB.EF = ED.AC


Hence, option (b) is true.
