sometimes... * * * * * No, never. Two angles are complementary angles if their measures sum to 90 degrees. An obtuse angle has a measure in the range (0, 90) degrees so two of them cannot sum to 90 degrees.
If you're talking about two angles adding up to equal a total measure of 90, then the answer to your question is complementary angles.
The sum of the angles of a triangle is 180 degrees. A right angle is 90 degrees. So the sum of the remaining two acute angles of a right triangle is 90 degrees.
Two angles are complementary if and only if their sum is 90 degrees.
True. -------------------------------------------------------------------- Two angles which are complementary have a sum which is 90° If the two angles are congruent, they are each half of 90° = ½ × 90° = 45° →The statement is true.
Two angles whose sum is 90 degrees are called complementary angles.
Complementary angles.
Right angles are 90°. The total measure of a triangle is 180°. So, the sum of the other two angles must equal 90°.
The sum of two complementary angles is 90 degrees.
They are a complementary pair of angles.

Angles that have a measure sum of 90.
Two angles with a sum of 90 are called complimentary angles.
Two angles that have the same measure and sum up to 90 degrees are complementary angles. For example, if one angle measures 45 degrees, the other angle will also measure 45 degrees, and their sum will be 90 degrees.
If two angles of a triangle each measure 45 degrees, the third angle measures 90 degrees. This is because of the Triangle Sum Theorem - The sum of the measure of the interior angles of a triangle is 180 degrees. If you know that two of the angles total to be 90 degrees, you can subtract that 90 degrees from the total 180. The result is 90 degrees.
