In a right angled triangle, the two non-right angles are complementary, because in a triangle the three angles add to 180°, and 90° has already been taken by the right angle. When two angles add to 90°, we say they "Complement" each other.

In geometry, complementary angles are defined as two angles whose sum is 90 degrees. In other words, two angles that add up to 90 degrees are known as complementary angles. For example, if angle A is 20 degrees, then its complement angle B would be 70 degrees because 20 degrees + 70 degrees = 90 degrees.
11 sty 2023 · What are complementary angles? Define complementary angles in geometry. Review the complementary angle theorems and find complementary angles with examples.
Complementary angles are a pair of angles that, when added together, equal 90°. In simpler terms, if you have ∠1 and ∠2, and their measures sum up to 90°, then ∠1 and ∠2 are considered complementary. We refer to ∠1 and ∠2 as each other's complements based on this relationship.

The complementary angles theorem states that two angles are complementary if they have the same measure (angle subtended by each side). In other words, they are inversely proportional to each other. Complementary angles can be used to create simple geometric shapes, like a right triangle or an isosceles triangle.
