In mathematics, the term “complementary” is used to describe angles or sets of angles that add up to a right angle, which is equal to 90 degrees. In other words, if two angles are complementary, the sum of their measures is 90 degrees.

To better understand the concept, let’s consider two angles, angle A and angle B. If angle A measures 30 degrees, then angle B is complementary to angle A if its measure is 60 degrees, since 30 + 60 = 90.

It’s important to note that the term “complementary” can also be used for sets of angles. For instance, a set of angles can be considered complementary if their sum is equal to a right angle. For example, a set of three angles measuring 20, 30, and 40 degrees would be considered a complementary set since their sum is 90 degrees.

Complementary angles are often seen in geometric shapes and trigonometry. They are commonly used to solve problems involving angles or to determine unknown angles when given complementary pairs.

In summary, complementary angles are angles that add up to 90 degrees, either individually or as part of a set. They play an important role in various areas of mathematics and geometry.
