COMPLEMENTARY ANGLE Meaning and
Definition
-
A complementary angle is a geometric term that refers to a pair of angles whose measures sum up to 90 degrees. When two angles are called complementary, it means that these angles are together sufficient to form a right angle, which is a perfectly straight 90-degree angle. In other words, they are said to complement each other, completing the right angle.
For example, if one angle measures 30 degrees, its complementary angle would measure 60 degrees since 30 + 60 equals 90 degrees. Similarly, if one angle measures 45 degrees, its complementary angle would measure 45 degrees as well, forming a right angle. It is important to note that the two angles do not have to be equal to be complementary; they only need to add up to 90 degrees.
Complementary angles have several uses in mathematics and geometry. They are often employed in the study of right triangles, as the sum of the two acute angles in a right triangle is always equal to 90 degrees. Complementary angles are also utilized in trigonometry to solve various mathematical problems and find missing angles or lengths in different geometric figures.
Overall, complementary angles hold a significant place in mathematics due to their relationship with right angles and their applications in various geometric contexts.

Etymology of COMPLEMENTARY ANGLE
The word "complementary" originates from the Latin word "complementum", which means "completion" or "fulfillment". In mathematics, it refers to the concept of angles that complete or add up to a right angle. Therefore, the term "complementary angle" is derived from the idea that these angles complete each other to form a whole right angle.
