They are alike because they both cross each other. They are different because perpendicular lines have to be a right angle while intersecting lines can be any kind of angle.

Perpendicular lines are a subset of intersecting lines. The only difference is that perpendicular lines intersect at an angle of 90o, whereas intersecting lines can converge at any angle.
No. If the lines are parallel they will never meet or intersect at any point. If the lines are perpendicular they do intersect, but perpendicular lines are a special case of intersecting lines. Perpendicular lines are exactly 90 degrees from each other. Intersecting lines do not haveto be perpendicular... but perpendicular lines are always intersecting.
Intersecting lines that form a right angle are perpendicular lines.
perpendicular crosses at a right angle, while intersecting lines don't
If lines were not perpendicular,they would either be intersecting or parrallel.
