Definition
Complementary angles are two angles whose measures add up to 90 degrees.
Description
Complementary angles are a fundamental concept in geometry, often used in solving problems involving right triangles and angle relationships. They are frequently encountered in trigonometry, where the sine of an angle is equal to the cosine of its complement. In real-world applications, complementary angles are used in design and architecture to ensure that elements fit together correctly, such as in the construction of right-angled structures. In education, understanding complementary angles helps students develop skills in angle measurement and geometric reasoning, forming a basis for more advanced studies in mathematics.
