How is the concept of complements defined?

The concept of complements is defined as separate things that, when combined, form a whole. In mathematics, this often refers to angles, sets, or other quantities. For instance, in the context of angles, two angles are said to be complementary if their measures add up to 90 degrees. Similarly, in set theory, the complement of a set refers to all the elements not in that set, which together with the original set, encompass the entire universal set.

Understanding complements in this way is essential in various branches of mathematics, as it helps establish relationships between different entities and allows for comprehensive problem-solving and reasoning.
