To prove that VUTS is a parallelogram, we can use the given congruence of triangle SVX and triangle UTX, as well as the fact that line segment SV is parallel to line segment TU.
Here is a complete two-column proof:
1. triangle SVX is congruent to triangle UTX 5. Given
2. line segment SV is parallel to line segment TU 6. Given
3. angle SVX is congruent to angle UTX 7. Corresponding parts of congruent triangles are congruent (CPCTC)
4. angle VUT is congruent to angle STU 8. Alternate interior angles are congruent (theorem for parallel lines)
5. line segment SV is congruent to line segment TU 7. Corresponding parts of congruent triangles are congruent (CPCTC)
6. line segment VT is congruent to line segment US 8. Triangle congruence by Side-Side-Side (SSS)
7. VUTS is a parallelogram 4. A quadrilateral with both pairs of opposite sides congruent and parallel is a parallelogram (definition of a parallelogram)
Therefore, we have proven that VUTS is a parallelogram.

Your teacher will grade your response for the following question to ensure that you receive proper credit for your answer.
Given: Triangle SVX is congruent to triangle UTX and line segment SV is parallel to line segment TU. Prove: VUTS is a parallelogram.
The image of a quadrilateral is shown. Its four vertices are labeled V, U, T, and S. One diagonal is drawn from vertex S to vertex U. Another diagonal is drawn from vertex T to vertex V. The two diagonals intersect in the middle of the quadrilateral at a point labeled X.
Complete the two-column proof.
