Question

select the angle pair which are linear angles.

∠2 and ∠6

∠6 and ∠7

∠5 and ∠7

∠1 and ∠7

Explanation:

Step1: Recall linear - angle definition

Two angles are linear if they are adjacent and their non - common sides are opposite rays, and they add up to 180°.

Step2: Analyze each option

• For ∠2 and ∠6, they are corresponding angles, not linear.
• For ∠6 and ∠7, they are adjacent and form a straight - line (their non - common sides are opposite rays), so they are linear angles.
• For ∠5 and ∠7, they are vertical angles, not linear.
• For ∠1 and ∠7, they are neither adjacent nor in a linear relationship.

Answer:

B. ∠6 and ∠7
