Question

If ∠ABC = 70o, then find

(i) ∠DGC

(ii) ∠DEF

Answer 1

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)]
