Question

O.No.4. Find the value of unknown angles
in the given figure
60
E

Answer 1

<2=120

<3=60

<4=120

<5=60

<6=120

<7=60

<8=120

*Explanation*

<1+<2=180––– angles in linear pair are supplementary

<2+60=180

<2=120

<2=<6=120------- corresponding angles are congruent

<1=<5=60---- corresponding angles are congruent

<3+<6=180----- interior angles are supplementary

<3+120=180

<3=60

<4+<5=180-- interior angles are supplementary

<2=<8=120------ alternate exterior angles are congruent

<1=<7=60--- alternate exterior angles are congruent
