Question

the measures of one angle of a parallelogram is 80 degree. what are the measures of the remaining angle

Answer 1

the other angle are 80 degree, 180-80=100 degree, 100 degree.
this is because of sum of cointerior angle forming in parallogram and it's opposite angle are equal

Answer 2

Let the angle A=80 degrees

Angle C also =80 [in a parallelogram opposite angles are equal]

Angle A + angle B=180

Angle B=100

similarly angle D=100
