Question

ABCD is a parallelogram and B is equal to 80 degree angle. Find the remaing angles
​

Answer 1

Answer:

Step-by-step explanation:

Data: ABCD is a parallelogram

angle A=angle C

and angle B=angle D

To find : angle A ,C,D

Proof :Since angle B =angleD

implies angle D=80°

In a parallelogram adjacent angles are complimentary

Therefore angle B + angle D=180°

80 + D= 180

D=100°
