Theory:

Complementary angles: Two angles are called Complementary angles if their sum is \(90°\).
Example:
The angle pair \(35°\) and \(55°\) are complementary, where the angle \(35°\) is said to complement of the other angle \(55°\), and vice versa. The sum of two angles \(35°\) and \(55°\) is \(90°\).

Supplementary angles: Two angles are called Supplementary angles if their sum is \(180°\).
Example:
The angle pair \(70°\) and \(110°\) are supplementary, where the angle \(70°\) is said to supplement of the other angle \(110°\), and vice versa. The sum of two angles \(70°\) and \(110°\) is \(180°\).
