Question

Parallel lines and intersecting lines are perpendicular lines explained

Answer 1

parallel lines never touch, intersecting lines cross, and perpendicular lines cross at a 90 degree angle. Hope that helped.

Answer 2

parallel lines are two lines in the same plane that will never intersect with each other. Intersecting lines are lines that pass through each other at some point. perpendicular lines are lines that intersect each other at 90 degree angles.
I hope this helps.
