Construction, engineering, drawing, and architecture all use parallel and perpendicular lines. Other than that, it is an important topic because you are learning how to apply the language and tools of mathematics to an intuitive system. These topics have proven important in the history of human kind and also many before you have shown that by learning about parallel and perpendicular lines, one learns how to use math and logic. It is doubtful that you can make a living off of parallel and perpendicular lines, but if you can't understand parallel and perpendicular lines, then I worry about your future.
Perpendicular is mostly used to describe Shapes and their properties. It means when two lines meet up at a 90 degrees right angle. It might be an X or a T when you look at it. Like the example shown below:------------------------------------lllllSo that isn't a good drawing, but it does show you the meaning of perpendicular!
