As far as we know, two lines can be perpendicular,
or they can be parallel, but they can't be both.
Take any two lines and look at their slopes. -- If the slopes are equal, then the lines are parallel. -- If the product of the slopes is -1, then the lines are perpendicular.
These lines are perpendicular: _|

They look like two intersecting lines that make four right angles. Like the two lines in this L.

It looks like a ladder with only one step, a railroad track with only one tie, or the upper-case letter ' H '.
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.

kinda like this.... / \ / \ the lines on the top and bottom are parallel kinda like this.... / \ / \ the lines on the top and bottom are parallel
Perpendicular is when two lines cross and form a right angle, which I hope you know what that is.
Just like this: ___________________ ____________________ parallel means they never intersect (touch)
What must be true? In your example, we have 4 intersecting lines. g and b are parallel, and f and h are parallel. g and b are perpendicular to f and h. It might look like tic-tac toe for example
They are straight lines that intersect each other at 90 degrees
