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.

11 sty 2023 · Complementary angles theorem. Two theorems make use of complementary angles. One states, “Complements of the same angle are congruent.” This theorem, which involves three angles, can also be stated in another way:
Three or more angles cannot be complementary even if their sum is 90 degrees. If two angles are complementary, each angle is called the "complement" or "complement angle" of the other angle. Two acute angles of a right-angled triangle are complementary.
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.
Complementary angles can be adjacent or non-adjacent. For a right triangle, the two non-right or oblique angles must be complementary. In right triangle ABC above, ∠B = 90° and ∠A + ∠C = 90° so, the nonadjacent angles A and C are complements of each other.
21 lis 2023 · If two angles are complementary, then each one of them is the complement of the other angle. They can be either adjacent (sharing the same vertex) or non-adjacent (formed at different...
Angle Pair: Complementary Angles. Understand that complementary angles are angle pairs which have a sum of 90 degrees, forming a right angle when paired together. Note, the two angles may be adjacent or not to be considered complementary.
