In order to find the complementary pair of angles, add the angles to get 90o. And to find the supplementary pair, the angle sum should amount to 180o.
(a) 68o, 112o
Sum = 68o + 112o = 180o
Thus, it is a supplementary pair of angles.
(b) 55o, 35o
Sum = 55o + 35o = 90o
Thus, it is a complementary pair of angles.
(c) 79o, 101o
Sum = 79o + 101o = 180o
Thus, it is a sumpplementary pair of angles.
(d) 64o, 26o
Sum = 64o + 26o = 90o
Thus, it is a complementary pair of angles.
