WEBVTT 99:59:59.999 --> 99:59:59.999 Hello, friends! 99:59:59.999 --> 99:59:59.999 We learned that the ray is a line segment 99:59:59.999 --> 99:59:59.999 wjth a beginning point to an endless point. 99:59:59.999 --> 99:59:59.999 So it extends from one direction only. 99:59:59.999 --> 99:59:59.999 But what happens if the line segment extends from two directions? 99:59:59.999 --> 99:59:59.999 If the line segment extends from two directions 99:59:59.999 --> 99:59:59.999 to an endless point and we can't measure its length, 99:59:59.999 --> 99:59:59.999 it's called a straight line. 99:59:59.999 --> 99:59:59.999 And a straight line like, this, AB or BY 99:59:59.999 --> 99:59:59.999 and a small line with two arrows above it. 99:59:59.999 --> 99:59:59.999 My friends, I hope you learned the difference 99:59:59.999 --> 99:59:59.999 between the line segment, the ray, and the straight line.
