In the given figure, the arms of two angles are parallel. If ∆ABC = 70°, then find:, (i) ∠DGC (ii) ∠ DEF

(i) Given, AB || DE and BC is a transversal line and ∠ABC = 70°
∵ ∠ABC = ∠DGC [Corresponding angles]
∴ ∠DGC = 70° ……….(i)

(ii) Given, BC || EF and DE is a transversal line and ∠DGC = 70°
∵ ∠DGC = ∠DEF [Corresponding angles]
∴ ∠DEF = 70° [From equation (i)]
