Step 1 :Given: \(\triangle SVT \cong \triangle SWT\)
Step 2 :\(\angle VST \cong \angle WST\) because corresponding parts of congruent figures are congruent
Step 3 :By the definition of an angle bisector, \(\overline{ST}\) bisects \(\angle VSW\)
Step 4 :Final Answer: \(\boxed{Given \triangle SVT \cong \triangle SWT, it follows that \angle VST \cong \angle WST. Therefore, \overline{ST} bisects \angle VSW. Hence, the statement is proven.}\)
