Question

How are parallel and perpendicular lines alike?

Answer 1

Perpendicular lines intersect each other at a point making an angle 90 degree.

And,

Parallel Lines never intersect each other .

hope it helps.. :)

Answer 2

Parallel lines are lines in a plane that are always the same distance apart. Parallel lines never intersect. Perpendicular lines are lines that intersect at a right (90 degrees) angle.

Parallel lines have the same slope and will never intersect. Parallel lines continue, literally, forever without touching (assuming that these lines are on the same plane). On the other hand, the slope of perpendicular lines are the negative reciprocals of each other, and a pair of these lines intersects at 90 degrees.
