Describe two lines that are in the same plane and do not intersect. perpendicular lines parallel lines
Perpendicular lines are two lines that intersect at a 90-degree angle. For example, if we consider a horizontal line and a vertical line on a piece of paper, they are perpendicular lines. Both lines lie in the same plane but do not intersect.
Parallel lines, on the other hand, are two lines that never intersect, regardless of how long they are extended. They stay at a constant distance apart from each other. For instance, the tracks of a railway are parallel lines as they run side by side, never intersecting each other while lying in the same plane.
