The figure shows two parallel lines PQ and ST cut by the transversals PT and QS. PQ and ST are parallel lines and PT and QS are transversals. The transversals intersect at R. Angle RPQ is labeled 1, angle PQR is labeled 2, angle PRQ is labeled 3, angle SRT is labeled 4, angle RST is labeled 6, and angle RTS is labeled 5.

Which statement best explains the relationship between Triangle PQR and Triangle TSR?
