4. Recall the concept of special pair of angles

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.

Supplementary angles: Two angles are called Supplementary angles if their sum is

$180°$ .

Example:

$180°$ is the sum of the angle whose measures

$70°$ and

$110°$ given in the figure. When two angles are supplementary, it is said that each angle is the addition of the other.
