In the given figure, the arms of two angles are parallel. If ∠ABC = 70°, then find: (i) ∠DGC (ii) ∠DEF |
|
Answer» (i)Given, AB DE and BC is a transversal line and ∠ABC = 70° ∵ ∠ ABC = ∠ DGC [Corresponding angles] Therefore, ∠DGC = 70° ……….(i) (ii) Given, BC EF and DE is a transversal line and ∠DGC = 70° ∵ ∠ DGC = ∠ DEF [Corresponding angles] Therefore, ∠ DEF = 70° [From eq. (i)] |
