Question Analysis

This question involves identifying which angle forms an alternate exterior angle pair with an angle when a transversal intersects two lines. The main focus is on understanding the concept of linear pair angles and their properties.

 

Key Concept Explanation

Alternate exterior angles are the angles that located outside the two intersected lines and on opposite sides of the transversal.

 

Option Analysis

Option A: ∠1 and ∠9 are in the same relative position at each intersection, making them corresponding angles.

Option B: ∠2 and ∠9 are on the same side of the transversal () and outside the two lines ( and ), making them same side exterior angles.

Option C: ∠3 and ∠9 are on opposite sides of the transversal () and outside the two lines (
