Web(c) BC · DE = AB · EF Explanation: We know that, If sides of one triangle are proportional to the side of the other triangle, and the corresponding angles are also equal, then the triangles are similar by SSS similarity. So, ∆ABC ∼ ∆EDF Using similarity property, AB/ED = BC/DF = AC/EF Taking AB/ED = BC/DF, we get AB/ED = BC/DF AB.DF = ED.BC
