Question

In a parallelogram if one angle is 80 then other angles are

Answer 1

Hi ,

******************************

In a parallelogram ,

i ) adjacent angles are supplementary.

ii ) Opposite angles are equal.

*********************************

Let ABCD is a parallelogram ,

if <A = 80°

<A + <B = 180

80 + <B = 180

<B = 180 - 80 = 100°

Therefore ,

<A = <C = 80°

<B = <D = 100°

I hope this helps you.

Answer 2

If one of the angle is 80 so, the others angle will be like this___
The angle opposite to 80 will also 80 (opposite angles are equal)
The angle adjacent to 80 will 180-80=100 (interior angles)
similarly, one more angle that opposite to 100 will 100.
