Question

which angles are alternate interior angles?
∠3 and ∠5
∠1 and ∠7
∠3 and ∠7
∠4 and ∠5

Explanation:

Step1: Recall alternate - interior angles def.

Alternate - interior angles are between two parallel lines and on opposite sides of the transversal.

Step2: Analyze each option.

For parallel lines \(s\) and \(t\) with transversal \(r\), \(\angle3\) and \(\angle5\) are between \(s\) and \(t\) and on opposite sides of \(r\).

Answer:

\(\angle3\) and \(\angle5\)
