The complementary angle theorem states, "If two angles are complementary to the same angle, then they are congruent to each other". Proof of Complementary Angles Theorem: We know that complementary angles exist in pairs and sum up to 90 degrees.

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.
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.
11 sty 2023 · Complementary angles theorem. Since two angles must add to 90°, if one angle is given – we will call it ∠GUM – only one other measurement can be its complement. If one angle is complementary to ∠GUM – we will call it ∠CAP – then any other angle that is also complementary to ∠GUM must be equal in measure to ∠CAP. Here is the ...
Congruent Complements Theorem. If two angles are complements of the same angle (or of congruent angles), then the two angles are congruent. Congruent Supplements Theorem. If two angles are supplements of the same angle (or of congruent angles), then the two angles are congruent. Right Angles Theorem. All right angles are congruent.
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. You can determine the complement of a given angle by subtracting it from 90°.
