How are perpendicular lines and interesting line alike? how are they different?

Perpendicular lines and intersecting lines are the same because they both describe 2 lines that cross one another...

They are different because perpendicular lines cross one another in a specific way.  The intersection of perpendicular lines forms 90 degree angles, while intersecting lines just describes 2 lines crossing.  It could be at any angle.

Perpendicular lines= two line segments are perpendicular if they meet at the right angle.
Intersecting lines= two line segments that cross at any angle.
the difference is perpendicular lines have to cross at a right angle. intersecting lines that cross at any angle
the similarity is because they both cross each other.
