Question

which angles are alternate interior angles with angle 3?
∠5 and ∠13
∠7 and ∠15
∠6 and ∠16
∠8 and ∠14

Explanation:

Step1: Recall alternate - interior angles definition

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

Step2: Identify transversals and relevant lines

For the angles formed by lines \(r\), \(s\), \(t\), \(u\), when considering the appropriate transversals, \(\angle3\) has alternate - interior angles \(\angle7\) and \(\angle15\).

Answer:

\(\angle7\) and \(\angle15\)
