### Instruction: help me answer this question In the figure given, PQ || RS. Find the measure of ∠R., think step by step
### Assistant: Since PQ is parallel to RS, then ∠PRQ = ∠QRS. Also, ∠PRQ and ∠R are vertical angles, so they are equal in measure. Therefore, ∠R = ∠PRQ = 60 degrees. , The answer is ∠R measures 60 degrees.
