Multiple Choice

For every 10 yards on a
football field, there is a boldly
marked line labeled with the
amount of yards. Each of
those lines is perpendicular to
both sidelines. What can be
said about the relationship of
the sidelines? Justify your
answer.
(1 point)
The sidelines are
perpendicular to each
other by the definition
of the Transitive
Property.
The sidelines are
parallel by the SameSide Interior Angles
Theorem.
The sidelines are
perpendicular by the
Perpendicular
Transversal Theorem.
The sidelines are
parallel because they
are perpendicular to

each of the yard lines on the field, which are themselves perpendicular to the sidelines. This demonstrates the relationship of parallel lines, as they do not intersect and are equidistant at every point. Therefore, the correct answer is: The sidelines are parallel by the Perpendicular Transversal Theorem.
