Definition Of Complementary Angles
What Are The Characteristics Of An Complementary Angles?
in geometry have the following characteristics. When two adjacent angles add up to 90° degrees they are called Complementary Angles. For an example, closely look at the picture below. We have a
which is a 90° angle. This 90° angle is cut in two by
. So now the 90° is divided in to two smaller angles that add up to 90°. Now let us express this definition in geometric math terms.
Another way to say angles are complementary is if two angles next to one another are
Complementary angles have length but no width or height.
If we look at the diagram below, the two adjacent angles are
. The sum of these two angles are 90° because they form a right angle.
Let us assume that angle
is 65°. That means that 65° plus
equals 90°. Taken to the next step, 90° - 65° =
