Question

select the transversal connecting ∠1 and ∠9. then classify the relationship between ∠1 and ∠9 as alternate interior, alternate exterior, corresponding, or consecutive interior angles.

Explanation:

Step1: Identify the transversal

The line that intersects the lines containing ∠1 and ∠9 is line c.

Step2: Classify the angle - relationship

∠1 and ∠9 are on the same - side of the transversal c and between the two lines that c intersects. So, they are consecutive interior angles.

Answer:

Transversal: line c; Relationship: consecutive interior angles
