Question

∠ 1 and ∠ 2 are

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

Answer 1

adjacent angles

complementary angles

Explanation:

we know that

If two angles are complementary, then their sum is equal to 90 degrees

we have that

`m\angle 1+m\angle 2=90^o` ---> 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
