Question

In a plane, line N is parallel to line O, line O is parallel to P, and line L is perpendicular to line N. Which must be true?

Answer 1

If in a plane, line N is parallel to line O, line O is parallel to line P, and line L is perpendicular to line N, then line N must also be parallel to line P and line L must also be perpendicular to line P. If two coplanar lines are parallel, then any line perpendicular to one must be perpendicular to the other. Hope this helps!
