How to Identify Paths In this lesson, let’s learn how we Identify Paths. We’re going to name each of these figures and problem one, we are given three figures. Here’s the key thing that I want us to remember. When we look at the figure A, we see a line or a path that has arrows in both sides, an arrow means it can go on forever. When we a path with two arrows in both sides, this is called a Line. A Line can go on in both directions forever. Now, you can have a horizontal line which is left to right or a vertical line which is top to bottom. So a line can be horizontal or vertical. It can be neither as long or it could just be angular line, but this one is a horizontal line. Let’s look at the second one. Here we see both the sides of the path. Both ends of the path have end points. This one end point, this is one end point. So when a line has two end points, that’s called a Line Segment. This is a Line Segment or this is a Line. A Line Segment obviously is part of a line that could go in all and both direction. A line segment ends right here. Now we have the third kind where it ends on one side but there’s an arrow on the other. This is called a Ray. A Ray starts on the given point and could go forever in one direction. That’s called a Ray. Key things to remember, Lines, Line Segments and Ray. Let’s try learning a little bit more about paths of lines. So here we see two lines that are crossing each other. Well, they are actually line segments because they got end points. So this one is line segments, both lines are segments. But there are intersecting lines segments, because they are crossing each other. They intersect here. Where in this case, we’ve got two lines and that go on forever in both directions but any given place, they are equidistant from one other. They will never meet. These are called Parallel Lines. Key thing to remember, if the lines crossed each other, they are intersecting. If they can never cross which means they stay the same distance apart everywhere, they are parallel lines.
