Question

In a parallelgram ABCD adjacent angles angleA and angle B are supplement.Given reasons

Answer 1

Answer:

if it is a parallelogram then

AD and BC will be parallel,

By interior angle theorem

angle A + B = 180

therefore angle A and B are supplementry

HOPE THIS WILL HELP YOU

Answer 2

n a parallelogram, opposite angles have equal lengths, and so in each parallelogram there are two pairs of equal angles. In a parallelogram, the angles add up to 360˚. Since there are two pairs of angles and one of each pair is on each side, adjacent angles are supplementary (their sum makes 180˚). therefore since angle A and angle B are adjacent, they are supplementary
