00:00:00,820 --> 00:00:09,040
In this video, let's discuss what we mean with angles, an angle is a figure or a shape formed by two

2
00:00:09,040 --> 00:00:11,790
race meeting at the common end point.

3
00:00:12,220 --> 00:00:14,200
Let's take an example here.

4
00:00:14,380 --> 00:00:18,120
We have a shape and this shape is what we call an angle.

5
00:00:18,460 --> 00:00:20,530
Let's name these points over here.

6
00:00:20,680 --> 00:00:21,100
All right.

7
00:00:21,340 --> 00:00:31,000
But we have point A to point B and point see, now, the two race are A, B and C, and the common endpoint

8
00:00:31,000 --> 00:00:32,050
is point eight.

9
00:00:32,530 --> 00:00:37,560
Now, point eight is called the vertex or the origin of the angle.

10
00:00:37,840 --> 00:00:41,260
And these are the arms of the angle.

11
00:00:41,680 --> 00:00:42,050
All right.

12
00:00:42,220 --> 00:00:44,180
Now, how do we indicate this angle?

13
00:00:44,380 --> 00:00:49,870
We draw a small curve over here to indicate this angle right now.

14
00:00:50,110 --> 00:00:51,060
What is the name?

15
00:00:51,070 --> 00:00:52,580
How do we call this angle?

16
00:00:52,810 --> 00:00:54,040
Let's see that next.

17
00:00:54,550 --> 00:01:01,760
This angle can be called angle E and note that this shape over here reads this angle.

18
00:01:02,140 --> 00:01:07,280
Now, we can also call this angle as angle B, E, C.

19
00:01:07,640 --> 00:01:08,490
Now, why is that?

20
00:01:08,500 --> 00:01:13,630
So if you trace this part B, E, C to get this shape back.

21
00:01:13,630 --> 00:01:13,960
Right.

22
00:01:14,200 --> 00:01:22,090
So this spot over here is B, C, that's why we call this angle as angle Biasi or angle it.

23
00:01:22,270 --> 00:01:25,360
Or we could also call this angle CAIB.

24
00:01:25,690 --> 00:01:26,800
All of it is the same.

25
00:01:26,980 --> 00:01:29,890
Now why do we have these two methods of calling the angle?

26
00:01:30,250 --> 00:01:32,080
Imagine the angle like this.

27
00:01:32,080 --> 00:01:35,100
If it was over here, you have one more over here.

28
00:01:35,110 --> 00:01:38,800
See right now if you see angle, it gets confusing, right?

29
00:01:38,950 --> 00:01:44,590
You don't know whether you mean this angle over here or this angle over here or this angle over here.

30
00:01:44,920 --> 00:01:52,060
But if we have point B over here, over here, say these over here and say, see over here, then if

31
00:01:52,060 --> 00:01:59,410
you want to talk about this angle over here, we can mention it as angle B B, so that's why it's convenient.

32
00:01:59,620 --> 00:02:03,040
And therefore, we have this way of naming angles.

33
00:02:03,190 --> 00:02:08,740
Now, if it's the case like this where you just have one angle over here, you can just call it angle

34
00:02:08,740 --> 00:02:09,070
eight.
