Question

select the transversal connecting ∠4 and ∠5. then classify the relationship between ∠4 and ∠5 as alternate interior, alternate exterior, corresponding, or consecutive interior angles.

Explanation:

Step1: Identify the transversal

Transversal is a line that intersects two or more lines. Line $d$ intersects the lines that $\angle4$ and $\angle5$ are on. So the transversal is line $d$.

Step2: Classify the angle - relationship

$\angle4$ and $\angle5$ are on the same - side of the transversal $d$ and between the two lines that $d$ intersects. According to the definition of consecutive interior angles, they are consecutive interior angles.

Answer:

The transversal is line $d$. The relationship between $\angle4$ and $\angle5$ is consecutive interior angles.
