Question

select all angles that form a pair of alternate interior angles with ∠3. ∠2 ∠5 ∠7 ∠8

Explanation:

Step1: Recall Alternate Interior Angles

Alternate interior angles are formed when a transversal crosses two parallel lines. They lie between the two lines and on opposite sides of the transversal.

Step2: Analyze the Diagram

In the diagram, the two vertical lines are parallel (implied by the transversal crossing them), and the horizontal lines are transversals. For $\angle 3$, we check the angles:

• $\angle 8$: $\angle 3$ and $\angle 8$ are between the two vertical lines, on opposite sides of the transversal (the vertical line). So they are alternate interior angles.
• $\angle 2$: Not between the lines.
• $\angle 5$: Not between the lines.
• $\angle 7$: Not between the lines.

Answer:

$\angle 8$ (the checkbox next to $\angle 8$ should be selected)
