In geometry, complementary angles are defined as two angles whose sum is 90 degrees. Two complementary angles when put together form a right angle. Learn the differences between complementary and supplementary angles.
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.
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.
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°.
