In mathematics, the term “complementary” refers to the angles that, when added together, result in a total of 90 degrees. Complementary angles are commonly found in geometry and trigonometry.
To further explain, let’s consider two angles, angle A and angle B. If the sum of angle A and angle B is 90 degrees, then angle A and angle B are complementary angles. This can be represented as:
A + B = 90 degrees
For example, if angle A measures 30 degrees, then angle B must measure 60 degrees in order for the sum to be 90 degrees. Similarly, if angle A measures 45 degrees, then angle B must measure 45 degrees to make the total sum 90 degrees.
Complementary angles are often found in right triangles, where one angle is 90 degrees. In this case, the other two angles are always complementary to each other.
It is important to note that complementary angles do not have to be adjacent or positioned close to each other. They can be located anywhere in a plane, as long as their sum is 90 degrees.
Knowing that angles are complementary can be helpful in solving various mathematical problems, particularly those involving geometry, trigonometry, and angles in general.
