Q.6 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


Answer :

\(\angle \) 1 + \(\angle \)2 = 180° (given)
If \(\angle \) 1 is decreased by some degrees, then angle 2 will also be increased by the same degree so that the two angles still remain supplementary.
