Three students attempt to define what it means for lines I and $$m$$ to be parallel. ![](http://admin.getprephub.com/media/editor/pt2_20230124194255897510.png) Daniela, Ori and Kaori have given three different definition of a line segment. Which of them is correct? ![](http://admin.getprephub.com/media/editor/pt2s_20230124194329520537.png)

Daniela's definition is a definition of perpendicular lines, not parallel lines. Ori's definition says that lines are parallel if they go in the same direction. It seems like he has the right idea, but the language here is somewhat imprecise. the line to "go in a direction" does not give a clear idea. Kaori's definition is perfect.
