Question

if angleA and angleB are two Advent angle of a parrolegaram if angle A a70° the angleB ?​

Answer 1

Answer:

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)
