in the given figure,the arms of two angles are parallel,if Z ABC =70°,then find (i) Z DGC (ii)Z DEF​

Answer 1

$\huge\red{\mid{\fbox{\tt{Answer}}\mid}}$

given that:

sides of the two angles are parellel so AB // DGE

and line BGC // EF

1) if AB // DGE and BC is transveral line, then

<DGC = <SBC = 70° (corresponding angle)

2) if line BGC // EF and DE is transveral line, then

<DEF = <DGC = 70° (corresponding angle)
