Question

ABCD is a parallelogram and angle a =60 degree . find the remaining angle​

Answer 1

Answer:

Angle A =60°

Angle A=Angle C (Since, opposite angles are equal in a parallelogram.)

Similarly, Angle B=Angle D

Therefore, Angle A=C= 60°

Angle. B + Angle A = 180° (Since , Co- interior angles are supplementary)

Therefore, Angle B = 180-60=120°

Also , Angle D = 120°.
