Question

abCD is a parallelogram and angle a is 120 degree find other angle ​

Answer 1

Answer:

Angle a is 120 degree

Angle C is also 120 degree(opp. sides)

Angle b=angle d=180-120=60degree(as coi terior angles are supplementary)

Hopi it helps...

Answer 2

Answer:

Angle A= Angle C= 120° (Opposite angles of parallelogram are equal)

Angle B= Angle D (Opposite angles of parallelogram are equal)

Angle A+ Angle B+ Angle C+ Angle D= 360°

Angle A+ Angle B+ Angle A+ Angle B= 360°

120° + 120° + 2(Angle B) = 360°

2(Angle B)= 360°- 240°

Angle B= 120/2

Angle B= 60°

And Hence,

Angle C= Angle B= 60°
