Question

practice with linear pairs and vertical angles. 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, and the sum of the measures of a linear pair of angles is 180°.

Step2: Analyze ∠SRT and ∠TRV

They are adjacent and their non - common sides RS and RV are opposite rays. So, they are a linear pair.

Step3: Analyze ∠SRT and ∠TRU

They are not adjacent, so they are not a linear pair.

Step4: Analyze ∠VRW and ∠WRS

They are adjacent and their non - common sides RV and RS are opposite rays. So, they are a linear pair.

Step5: Analyze ∠VRU and ∠URS

They are not adjacent, so they are not a linear pair.

Step6: Analyze ∠URW and ∠WRS

They are not adjacent, so they are not a linear pair.

Answer:

∠SRT and ∠TRV, ∠VRW and ∠WRS
