Either perpendicular lines if the lines create 90o angles or intersecting lines.
Non-perpendicular intersecting lines. There is no special name.
Sometimes.Perpendicular lines always intersect.Parallel lines never intersect.Therefore, intersecting lines may be perpendicular, but not always.
There is none.
No but parallel lines never meet
Two or more lines that meet at a point are called intersecting lines.
Lines intersect if the meet at one point. Perpendicular lines also meet at one point, but their intersection is a right angle. Intersecting lines in the plane do not meet at two points.
Intersecting lines are lines that meet at a point. In other words lines that cross each other (like an X).
No, because although perpendicular and intersecting lines do touch, parallel lines never meet.
Intersection or Intersecting Lines
Yes, otherwise they wouldn't be intersecting.
