Question

Which relationship describes angles 1 and 2?

Select each correct answer.

vertical angles

complementary angles

supplementary angles

adjacent angles

Answer 1

Complementary angles

Adjacent angles

Explanation:

we know that

Two angles are complementary if their sum is equal to
`90\°`

In this problem

`m<1+m<2=90\°` -----> by complementary angles

Two angles are adjacent when they have a common side and a common vertex

In this problem

m< 1 and m<2 are adjacent angles, because have a common side and a common vertex
