1.2 Line Segments and Rays

In this lesson I will teach you about line segments and rays. A line segment is basically what the name implies- it's just a "piece" of a line with end points. Along with the definition of a line segment you need to understand the proper notation to describe a line segment. The next shape we will look at is the "ray". You can think of a ray like an arrow in the sense it has one starting point and travels out in specific direction. The key difference between a line segment and ray is that the line segment has two end points where as the ray only has one. The notation for a line segment and ray are similar so be careful not to confuse the two. Like I said in the previous lesson, geometry has lots of symbols and notations- you need to watch the details of these symbols as many will look a like. Lastly you need to ensure you practice after you watched the lesson it's a must if you expect to master the concepts. Good luck!
