Answer:
The sheets of metal are all perpendicular to the top line of the roof.
Step-by-step explanation:
The perpendicular transverse theorem shows that in a plane, if one line is perpendicular to one of two parallel lines, then it is perpendicular to the other line as well.
Based on that theorem, we can conclude that the sheets of metal are all perpendicular to the top line of the roof.
