Question

Identify the correct ways to classify ∠1 and ∠4 in the figure shown below.

Answer 1

They are adjacent and complementary.
Next to each other and add up to 90 degrees.

Answer 2

adjacent and complementary angles

Explanation:

we know that

If the sum of two angles is equal to
`90\°` then, the angles are Complementary

and

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

In this problem we have

`m<1+m<4=90\°` -----> by complementary angles

and

m<1 and m<4 have a common side and a common vertex

therefore

m<1 and m<4 are adjacent and complementary angles
