They are a complementary pair of angles.
Two angles whose sum is 90 degrees are called complementary angles.
Complementary
SUPPLEMENTARY ANGLES are two angles the sum of whose measures is 180 degrees.
Two angles whose measures have a sum of 90 degrees are called complementary angles. For example, if one angle measures 30 degrees, its complement would measure 60 degrees. Complementary angles can be adjacent or separate, and they are often used in various geometric contexts.
Two or more angles that sum to 90 degrees are called complimentary angles.
Two angles whose sum is 90 degrees are called complementary angles.

They are a supplementary pair of angles.
Two angles the sum of whose measures is 90 degrees are complimentary angles.
Two angles whose sum is 90 degrees are called complementary angles. Two angles whose sum is 180 degrees are called supplementary angles. A single angle of 90 degrees is called a right angle.
Supplementary angles have a sum of 180 degrees.
