Question Analysis

This question involves identifying which angle forms a same side interior 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

Same side interior angles are the angles that located inside the two intersected lines and on the same side of the transversal.

 

Option Analysis

Option A: ∠3 and ∠1 are non-adjacent angles, and they are directly opposite each other at the intersection point, making them vertical angles.

Option B: ∠8 and ∠1 are on the same side of the transversal () and inside the two lines ( and ), making them same side interior angles.

Option C: ∠10 and ∠1 are on the same side of the transversal () and inside the two lines ( and
