Question

In the given figure, $\angle 1$ and $\angle 2$ are supplementary angles. If $\angle 1$ is decreased, what changes should take place in $\angle 2$ so that both the angles still remain supplementary?

✓

Answer

Since, $ \angle 1$ and $ \angle 2$ are Supplementary angles
And if $ \angle 1$ is decreased than $ \angle 2$ must be increased by the same measure, so that the pair of both the angles remain supplementary. Here $ \angle 1$ is reduced by $1$ degree, so $ \angle 2$ must be increased by $1$ degree.
