If sum of two angles is 180° , then they are called supplementary angles.
If sum of two angles is 90° , then they are called complementary angles.
(i) 65° + 115° = 180° These are supplementary angles.
(ii) 63° + 27° = 90° These are complementary angles.
(iii) 112° + 68° = 180°These are supplementary angles.
(iv) 130° + 50° = 180° These are supplementary angles.
(v) 45° + 45° = 90° These are complementary angles.
(vi) 80° + 10° = 90° These are complementary angles.
