Each sheet of metal on a roof is
perpendicular to the top line of the
roof. What can you conclude about
the relationship between the sheets
of roofing? Justify your answer.
The sheets of metal are all parallel to
each other because in a plane, if a
line is perpendicular to one of two
parallel lines, then it is also
perpendicular to the other.
The sheets of metal are all parallel to
each other because in a plane, if two
lines are perpendicular to the same
line, then they are parallel to each
other.
The sheets of metal are all parallel to
each other by the Alternate Interior
Angles Theorem.
The sheets of metal are all parallel to
each other by the Transitive Property
of Parallel Lines.
