Answer:
adjacent angles
complementary angles
Step-by-step explanation:
we know that
If two angles are complementary, then their sum is equal to 90 degrees
we have that
[tex]m\angle 1+m\angle 2=90^o[/tex] ---> given problem
therefore
∠ 1 and ∠ 2 are complementary angles
Remember that
Two angles are Adjacent when they have a common side and a common vertex
In this problem
∠ 1 and ∠ 2 have a common side and a common vertex
so
∠ 1 and ∠ 2 are adjacent angles
