Final answer:
The measure of ∠pqv is half of the measure of ∠pqr since qv→ bisects ∠pqr, making the correct answer a) ∠pqr/2.
Step-by-step explanation:
If qv→ bisects ∠pqr, meaning it divides the angle into two equal parts, then the measure of ∠pqv would be half that of ∠pqr. This is because the definition of bisecting an angle is to split it into two congruent (equal) angles. So, the measure of ∠pqv is ∠pqr/2, which corresponds to option a) ∠pqr/2.
