As far as we know, two lines can be perpendicular, or they can be parallel, but they can't be both.
These lines are perpendicular: _|
They look like two intersecting lines that make four right angles. Like the two lines in this L.
They are straight lines that intersect each other at 90 degrees
Perpendicular lines look like two straight lines that meet or intersect at a 90-degree angle. The capital letter T is an example of what they might look like.

Perpendicular is when two lines cross and form a right angle, which I hope you know what that is.

It depends on how many sides the polygon has: An octogon has 8 lines of symmetry, a pentagon has 5......
7 lines put together
They are straight lines that intersect each other at right angles or 90 degrees.
Perpendicular lines are ones that make right angles when they meet. For instance the letters T H E and L are all made of perpendicular line segments.
A perpendicular line is two lines that look like a plus +. If they're not perpendicular, they don't cross with 90 degree angles.
