Definition of. Complementary Angle. more ... Two angles are Complementary when they add up to 90 degrees (a Right Angle). They don't have to be next to each other, just so long as the total is 90 degrees. Examples: • 40° and 50° are complementary angles. • 60° and 30° are complementary angles. • 5° and 85° are complementary angles.
These two angles (40° and 50°) are Complementary Angles, because they add up to 90°: Notice that together they make a right angle. But the angles don't have to be together. These two are complementary because 27° + 63° = 90°.
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.
Definition and properties of complementary angles - two angles that add to 90 degrees
Complementary angles are two angles whose measures have a sum of 90°. Each angle is the complement of the other. Complementary angles can be adjacent or non-adjacent. Adjacent complementary angles. Non-adjacent complementary angles. For a right triangle, the two non-right or oblique angles must be complementary.
When two angles are complementary, each angle is called the “complement” or “complementary” of the other. A right-angled triangle has two complimentary sharp angles. There are two types of complementary angles i.e. Adjacent Complementary angles and non-adjacent Complementary angles.
