प्रश्न
In the given figure, the arms of two angles are parallel.
If ∠ABC = 70°, then find
- ∠DGC
- ∠DEF
उत्तर
i. Consider that AB || DG and a transversal line BC is intersecting them.
∠DGC = ∠ABC (Corresponding angles)
∠DGC = 70°
ii. Consider that BC || EF and a transversal line DE is intersecting them.
∠DEF = ∠DGC (Corresponding angles)
∠DEF = 70°
