00:00:00,620 --> 00:00:05,320
In this video, let's discuss the interior angle biosecure theorem.

2
00:00:05,780 --> 00:00:09,110
All right, over here, we have Triangle Pedic.

3
00:00:09,110 --> 00:00:10,220
You all right?

4
00:00:10,400 --> 00:00:12,350
Now I have an angle over here.

5
00:00:12,350 --> 00:00:13,930
This is Angle Petechial.

6
00:00:14,240 --> 00:00:18,170
Now, let me draw the angle by sector of this angle over here.

7
00:00:18,650 --> 00:00:20,960
Let the angle by sector be D.F..

8
00:00:21,180 --> 00:00:21,620
Right.

9
00:00:21,800 --> 00:00:29,210
So angle one is equal to angle two because we have constructed the angle by sector now as per the interior

10
00:00:29,210 --> 00:00:33,740
angle biosecure theorem bitterly divided by dequeue.

11
00:00:33,740 --> 00:00:37,640
That's the two sides of the angle which was bisected.

12
00:00:38,120 --> 00:00:43,880
The ratio of these two sides will be equal to the ratio of BSF by RFQ.

13
00:00:44,030 --> 00:00:45,230
Let me that over here.

14
00:00:45,690 --> 00:00:49,250
Prebuy dequeue is equal to EPF by RFQ.

15
00:00:49,490 --> 00:00:53,150
Now remember, when you take the order, the order is important.

16
00:00:53,150 --> 00:00:58,010
You have taken beauty as the numerator and dequeue as the denominator.

17
00:00:58,010 --> 00:00:58,340
Right?

18
00:00:58,560 --> 00:01:03,530
So in the numerator over here you need to take the side which is closer to this side.

19
00:01:03,530 --> 00:01:08,200
So BFC should be the numerator and if you should be the denominator.

20
00:01:08,210 --> 00:01:09,710
So if you write it as if.

21
00:01:09,720 --> 00:01:11,900
Q By both, that would be wrong.

22
00:01:11,910 --> 00:01:14,470
Right, because you have taken it as prebiotic.

23
00:01:14,470 --> 00:01:16,970
Q Similarly, let's take one more case.

24
00:01:17,180 --> 00:01:19,340
You have an angle over here.

25
00:01:19,520 --> 00:01:21,740
Say this is the angle by sector, right.

26
00:01:21,950 --> 00:01:27,230
Let's write this as X, Y and E and B, what does this theorem say.

27
00:01:27,410 --> 00:01:34,130
It's divided by Y will be equal to a baby or B by its will be equal to a baby.

28
00:01:34,130 --> 00:01:34,430
Right.

29
00:01:34,430 --> 00:01:40,190
Because you've taken X over here, the numerator, so you need to put it, which is closer to X in the

30
00:01:40,400 --> 00:01:41,090
numerator.

31
00:01:41,090 --> 00:01:45,380
And this is what the interior angle bisecting theorem says.
