Question

In the given figure, the arms of two angles are parallel.If angle abc =70° then find

Answer 1

In the given figure , the arms of two angles are parallel. if ∠ABC=70

∘

, then find

(i) ∠DGC

(ii) ∠DEF

Solution

Given that:

Sides of the two angles are parallel so AB∥DGE and line BGC∥EF

i)If AB∥DGE and BC is transversal line, then

∠DGC=∠ABC=70

∘

(Corresponding angle)

ii)If line BGC∥EF and DE is transversal line, then

∠DEF=∠DGC=70

∘

(Corresponding angle)
