We are given that TUVW is an isosceles trapezoid.
The sides TU and WV are parallel.
Recall the property of isosceles trapezoid that the base angles are congruent.
This means that angle T is congruent to angle U and angle U is congruent to angle T
[tex]\begin{gathered} \angle T\cong\angle U \\ \angle U\cong\angle T \end{gathered}[/tex]Therefore, angle T and U are congruent.
