Question

linear pair alternate exterior corresponding vertical same - side interior alternate interior

Explanation:

Step1: Recall definitions

• Linear pair: Adjacent angles that form a straight line ($180^{\circ}$).
• Alternate exterior: Angles outside two parallel lines and on opposite sides of the transversal.
• Corresponding: Angles in the same position relative to parallel lines and transversal.
• Vertical: Opposite angles formed by two intersecting lines.
• Same - side interior: Angles inside two parallel lines and on the same side of the transversal.
• Alternate interior: Angles inside two parallel lines and on opposite sides of the transversal.

Step2: Analyze the figure

Assume the vertical lines are parallel (they have the same direction arrows). The transversal cuts through them. The angles in question (based on the general problem of classifying angle pairs in parallel - transversal setups) - alternate interior angles are non - adjacent, inside the parallel lines, and on opposite sides of the transversal.

Answer:

alternate interior
