Question

which angles are linear pairs? check all that apply.
□ ∠srt and ∠trv
□ ∠srt and ∠tru
□ ∠vrw and ∠wrs
□ ∠vru and ∠urs
□ ∠urw and ∠wrs

Explanation:

Step1: Recall linear - pair definition

Two angles are a linear pair if they are adjacent and their non - common sides are opposite rays.

Step2: Analyze each angle pair

• For ∠SRT and ∠TRV: They are adjacent and their non - common sides RS and RV are opposite rays, so they are a linear pair.
• For ∠SRT and ∠TRU: They are not adjacent in the way required for a linear pair.
• For ∠VRW and ∠WRS: They are adjacent and their non - common sides VR and RS are opposite rays, so they are a linear pair.
• For ∠VRU and ∠URS: They are not adjacent in the way required for a linear pair.
• For ∠URW and ∠WRS: They are not adjacent in the way required for a linear pair.

Answer:

∠SRT and ∠TRV, ∠VRW and ∠WRS
