Answer: 6 units
Step-by-step explanation:
Given : Figure TUVW ≅ figure ABCD,
AB = 12 units , CD = 6 units , and DA = 4 units .
We know that if two polygons are congruent then their corresponding parts are also congruent.
Therefore, if Figure TUVW ≅ figure ABCD, then its corresponding sides must be congruent.
Since the corresponding sides of VW is CD in figure ABCD.
Then the measure of VW = CD = 6 units
Hence, the measure of VW= 6 units
