We have proven that line TU is parallel to line VW as shown below. That is, TU || VW
Proof of angles
From the question, we are to prove that TU || VW
In the given image,
  Statements      Reasons
1. ST || UV Â Â Â Â Â Â Â Â Â Given
2. ∠T ≅ ∠U         Alternate angles
3. ∠T ≅ ∠V         Given
4. ∠U≅ ∠V         Substitution property
5. TU || VW Â Â Â Â Â Â Â Â Alternate interior angles theorem
NOTE: If the alternate interior angles formed by a transversal of two lines are equal, then the lines are parallel
Hence, we have proven that line TU is parallel to line VW. That is, TU || VW
