The question isn't clear. If the sum of the two angles is 90 degrees, then
they're called "complementary angles". If each one is a 90-degree angle,
then they're called "two right angles".

60 degrees and 120 degrees
Those angles are called complimentary angles. They add up to 90 degrees. Two angles that add up to 180 degrees are called supplementary angles.
Two angles that sum to 90 degrees are called complementray angles. The term is not usually applied to three or more angles that sum to 90 degrees.
23 degrees and 67 degrees
If two angles are complementary, then they equal 90 degrees. If one angle is 62 degrees we subtract it from 90 and get 38 degrees.
