Yes, if the sum of two acute angles is 90° they are said to be complementary. This is commonly seen with the two other angles in a right angled triangle.
This property leads to the sine of an angle equalling the cosine of its complement, and the tangent of an angle equalling the cotangent of its complement.
e.g. sin 26° = cos 64° : tan 37° = cot 53°

What are non examples of complementary angles?
Non-examples of complementary angles are pairs of angles that do not add up to 90 degrees. For instance, two angles measuring 40 degrees and 50 degrees together total 90 degrees, making them complementary; however, angles measuring 30 degrees and 70 degrees, which total 100 degrees, are not complementary. Similarly, angles of 0 degrees and 100 degrees, or 45 degrees and 60 degrees, also do not meet the complementary criteria.
If two angles are complementary the sum of their measures is 90 degrees. Two angles are complementary angles if and only if the sum of their measures is 90 degrees.?
Two angles are considered complementary if their measures add up to 90 degrees. This means that if the sum of two angles equals 90 degrees, they are classified as complementary. Conversely, if two angles are complementary, their measures must sum to 90 degrees. Thus, the statements effectively define the same relationship between complementary angles.
What is the sum of measures of complementary angles?
Complementary angles are two angles that add up to 90 degrees. Example: 50 and 40 degrees
What is the degrees of two angles if they are complementary?
Their sum is 90 Degrees.
What is the union of two complementary angles?
The sum of the angles is 90 degrees.
What is the sum of two complementary angles?
The sum of two complementary angles is 90 degrees. The sum of two supplementary angles is 180 degrees.
Two angles whose sum is 90 degrees?
two angles whose sum is 90 degrees is a complementary angle.
What are the two complementary angles?
There is an infinite number of complementary angles. Complementary angles are all angles that add up to 90 degrees, such as two 45 degree angles.
How do you write the biconditional for If two angles are complementary then their sum is 90 degrees?
Two angles are complementary if and only if their sum is 90 degrees.
What is a pair of complementary angles?
Complementary angles are two angles that add up to exactly 90 degrees.

Two angles that equal 90 degrees?
complementary angles.
Two angles that measure at 90 degrees?
complementary angles
What is the degrees of two angles if they are complementary?
Their sum is 90 Degrees.
Can an angle be complementary only if it is ninety degrees?
Yes. Anything two angles that add to 90 degrees is complementary. Anything two angles that add to 180 degrees is supplementary.
Two angles are congruent and complementary What are the measures of these angles?
90 degrees
If the sum of the measures of two angles is ninety degrees then the angles are what?
Complementary
