Two lines are parallel if they never cross one another. Another way to tell if they are parallel is if they have the same slope. Also, if the same line intersects both of them at a 90 degree angle, they would be parallel (in other words, if both lines are perpendicular to a common line, they are paraellel).

How can you determine if two lines are parallel?
There are three ways to find if two lines are parallel. The first one is to see if there is any indication. I there isn't, you should never trust your eyes. Instead, you should find the slope of each line. If they are then the two lines are parallel. Another way to find if two lines are parallel is to see if there are any corresponding angles, Alternate Interior Angles, and Alternate Exterior Angles. If there are and they are congruent, then the two lines are parallel.

What is the symbol for skew lines?
Well, darling, the symbol for skew lines is an "S" with a slash through it. It's like a big ol' "NOPE" sign for lines that will never meet no matter how much they try. So, if you see that symbol, just accept that those lines are going their separate ways and move on with your life.
