The following is an incomplete paragraph proving that ∠ wrs ≅ ∠ vqt given the information in the figure were :

according to the given information, vu is parallel to zw while angles squ and vqt are vertical angles. angle vqt is congruent to angle squ by the vertical angles theorem. because angles squ and wrs are corresponding angles, they are congruent according to the corresponding angles postulate. finally, angle vqt is congruent to angle wrs by the

which property of equality accurately completes the proof?

a. reflexive
b. substitution
c. subtraction
d. transitive
