Question

in the given figure the arms of two parallel angles are parallel.If angle ABC=70 degree , then find
(I)Angle DGC
(ii)Angle DEF​

Answer 1

Answer:

Angle DGC = 70° Angle DEF = 70°

Step-by-step explanation:

Since AB is parallel to DG then by alternate interior angles property angle DGC will be 70 degree.

Same for angle DEF.

Answer 2

Answer:

$\huge\bf\underline\red{answer} \\ \\ \tt\angle \:DGC \: = 70\degree \\ \\ \tt\angle \: DRF \: = 70\degree \\ \\ \\ \huge\bf\underline\red{solution:} \\ \\ \\ \\ \large\sf\underline\red{given \: that \: } \: \\→\tt AB//DE \\ \\ →\tt \: BC//EF \\ \\ \\ \therefore \sf\angle \: DGC \: \: = \sf(corresponding \: angle)\\→\sf70 \degree \\ \sf{\red{similarly}} \\ \\ \sf\angle \: DRF \: = 70\degree \\ \sf(corresponding \: angle) \\ \\ \\ \\ \sf\huge \: {hene \: verified}$
