Answer:
Angles 1 and 2 are Complementary angles
Step-by-step explanation:
There is probably some vocabulary is your lesson, but from my knowledge, these angles would be complementary because they add up to 90 degrees total. Complementary angles are either of two angles that add up to 90 degrees, since it is shown that the other three angles besides these two are 90 degrees (thats what the square signifies), then these two angles have to add up to 90 degrees as well which will make them complementary.
