complementary angles
Complementary angles are two angles that add up to 90 degrees
Complementary angles are two angles that add up to 90 degrees. In other words, when you add the measures of two complementary angles, the sum is always 90 degrees.
For example, if angle A measures 30 degrees, then angle B (which is complementary to angle A) would measure 60 degrees, because 30 degrees + 60 degrees = 90 degrees.
Complementary angles are often found in right triangles, where one angle is a right angle measuring 90 degrees. The other two angles in a right triangle are complementary to each other.
It is important to note that complementary angles do not have to be adjacent (side-by-side) or next to each other. They can be anywhere in a geometric figure as long as their angle measures add up to 90 degrees.
Complementary angles are useful in many areas of mathematics, such as geometry and trigonometry. For example, in trigonometry, the sine and cosine functions are defined using right triangles, and the measures of complementary angles play a significant role in calculating trigonometric ratios.
To summarize, complementary angles are two angles that add up to 90 degrees. They can be found in various geometric figures and have applications in different branches of mathematics.
