∠1 and ∠ 2 are

-adjacent angles
-supplementary angles
-right angles
-vertical angles

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

---> 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

step-by-step explanation:

2nd one in the first row is correct
