Question 1098240: Hello!
Thanks for checking my question out!
____
1. For every 10 yards on a football field, there is a boldly marked line labeled with the amount of yards. There are two parallel sidelines on each side of the field. If the 50 yard line is perpendicular to one of the sidelines, what is its relationship to the other sideline?
An image of a football field is shown. There are two horizontal sidelines labeled and there are evenly spaced vertical lines across the field. From left to right they are labeled 10, 20, 30, 40, 50, 40, 30, 20, 10. (1 point)

a) The 50 yard line is parallel to the other sideline by the Perpendicular Transversal Theorem.

b) The 50 yard line is perpendicular to the other sideline by the definition of the Transitive Property.

c) The 50 yard line is parallel to the other sideline by the Same-Side Interior Angles Theorem.

d) The 50 yard line is perpendicular to the other sideline by the Perpendicular Transversal Theorem.
Could someone please help me with this problem?
Thanks!
