Answer
Final Answer: \(\boxed{Given \triangle SVT \cong \triangle SWT, it follows that \angle VST \cong \angle WST. Therefore, \overline{ST} bisects \angle VSW. Hence, the statement is proven.}\)
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: \(\boxed{Given \triangle SVT \cong \triangle SWT, it follows that \angle VST \cong \angle WST. Therefore, \overline{ST} bisects \angle VSW. Hence, the statement is proven.}\)
