Either intersecting lines or perpendicular lines
parallel lines
They are called parallel lines, provided they remain the same distance from each other.
intersecting lines
Lines that that intersect each other at right angles on a plane are perpendicular lines.
Either intersecting lines or perpendicular lines
Just because they cross over each other doesn't mean they aren't still called lines.
Lines that cross each other at 90 degrees are perpendicular lines.
parallel lines
intersecting lines...
They are called parallel lines, provided they remain the same distance from each other.
Yes, well the don't have to cross they can just run into each other
No, parallel lines are the ones that never cross each other. Perpendicular lines form an x.
Yes.
intersecting lines
Intersecting lines are, lines that cross over each other just like intersections on the road, which are cross sections from each end.
Lines that that intersect each other at right angles on a plane are perpendicular lines.
