$\overset\longleftrightarrow{PS}\parallel\overset\longleftrightarrow{QT}$
The Converse of the Corresponding Angles Theorem tells us that if congruent corresponding angles are formed when a line transverses two other lines, the two lines are parallel. The diagram shows congruent corresponding angles, where $\overset\longleftrightarrow{PQ}$ intersects $\overset\longleftrightarrow{PS}$ and $\overset\longleftrightarrow{QT}$
