Answer:
Notice that statement number 3:
[tex]\Delta STU\cong\Delta VUT[/tex]
is wrong because the corresponding vertices are:
[tex]\begin{gathered} S\leftrightarrow V, \\ U\leftrightarrow U, \\ T\leftrightarrow T. \end{gathered}[/tex]
Therefore, the right statement should be:
[tex]\Delta STU\cong\Delta VTU\text{.}[/tex]
