Question

The measure of one angle of a parallelogram is 80°. What are the measures of the remaining angles? ​

Answer 1

Answer => let the all 4 angle of parallelogram are A , B ,C , D

let A = 80

then B = 180-80 = 100

C = A (opposite angle s)

C = 80

D = B (opposite angle )

D = 100

Answer 2

Opposite angle would be 80 d

Let The adjacent be x
x= 180-80 =100 d

Then its opposite is 100 d.
