What is the relation between the two straight lines?
We notice almost immediately that these two lines intersect. That makes them intersecting lines. It also means they can not be parallel lines because they intersect. We can also say that these two lines are not perpendicular.
What we did here is we drew a line that would be perpendicular to these lines. But we’ve been given no indication that these angles measure 90 degrees. So we can say that they’re not perpendicular. But they are intersecting. The relation between these two straight lines is intersecting but not perpendicular.
