1 99:59:59,999 --> 99:59:59,999 Hello, friends! 2 99:59:59,999 --> 99:59:59,999 We learned that the ray is a line segment 3 99:59:59,999 --> 99:59:59,999 wjth a beginning point to an endless point. 4 99:59:59,999 --> 99:59:59,999 So it extends from one direction only. 5 99:59:59,999 --> 99:59:59,999 But what happens if the line segment extends from two directions? 6 99:59:59,999 --> 99:59:59,999 If the line segment extends from two directions 7 99:59:59,999 --> 99:59:59,999 to an endless point and we can't measure its length, 8 99:59:59,999 --> 99:59:59,999 it's called a straight line. 9 99:59:59,999 --> 99:59:59,999 And a straight line like, this, AB or BY 10 99:59:59,999 --> 99:59:59,999 and a small line with two arrows above it. 11 99:59:59,999 --> 99:59:59,999 My friends, I hope you learned the difference 12 99:59:59,999 --> 99:59:59,999 between the line segment, the ray, and the straight line.
