To prove that 2 lines are parallel find the pair of corresponding angles equal in measure
From the given figure
Then the statement 3 is
[tex]m\angle RTS+m\angle STW=180^{\circ}\rightarrow\text{ Angles forming a linear pair sum to 180}^{\circ}[/tex]
Since we prove that Then VX // SU
Then the statement 6 is
VX // SU ---------- Converse of Corresponding Angles Theorem
