pairs of angles
Two angles are complementary
to each other if they add upto 90° [See Fig.
4.28(i)] Two angles are supplementary to each
other if they add upto 180° [See Fig. 4.28(ii)]
In the above figures, 20° and 70° are complementary
angles and 147° and 33° are supplementary angles. But 35° and 75° are neither complementary
nor supplementary.
