00:00:00,630 --> 00:00:06,290
In this video, let's discuss what we mean with a ray area is a portion of a line.

2
00:00:06,960 --> 00:00:08,170
Let's take an example.

3
00:00:08,460 --> 00:00:09,930
This is an example of a right.

4
00:00:10,170 --> 00:00:12,810
You can see that it has a clear starting point.

5
00:00:13,110 --> 00:00:16,710
And in the other direction, it keeps going on endlessly.

6
00:00:17,070 --> 00:00:21,010
Now, let me call this point and let this be point B.

7
00:00:21,270 --> 00:00:25,080
Now, this right over here can be called rapee.

8
00:00:26,850 --> 00:00:30,280
Point eight is the starting point of this.

9
00:00:30,900 --> 00:00:38,460
And you can see that point B is a point in the part of the race right now saying let me take another

10
00:00:38,460 --> 00:00:40,040
point in the part of the race.

11
00:00:40,050 --> 00:00:46,040
That would be point B so I could call this either A, B or a B, both are the same.

12
00:00:46,050 --> 00:00:48,660
These two will represent the same race.

13
00:00:49,050 --> 00:00:49,470
All right.

14
00:00:49,710 --> 00:00:54,310
Now, an important point to note over here is you cannot call this rapee.

15
00:00:54,570 --> 00:00:55,840
That would be wrong, right?

16
00:00:56,070 --> 00:01:01,470
You cannot call it Ripia, because this point over here has to be the starting point.

17
00:01:02,010 --> 00:01:07,640
And this point over here has to be a point in the direction of the part of the race.

18
00:01:07,650 --> 00:01:09,330
And that would be the opposite direction.

19
00:01:09,340 --> 00:01:09,560
Right?

20
00:01:09,810 --> 00:01:11,670
Ripia would be something like this.

21
00:01:13,320 --> 00:01:19,210
If I just take this part over here and it keeps going on in this direction, that would be rape.
