1
00:00:00,780 --> 00:00:07,770
Let's do this question in the figure is the midpoint of both HCN beauty, and then we need to choose

2
00:00:07,770 --> 00:00:11,350
among eight to be rich, set of angles are equal.

3
00:00:11,700 --> 00:00:12,150
All right.

4
00:00:12,450 --> 00:00:15,970
Pause the video, give it a try and then let's do it together.

5
00:00:16,560 --> 00:00:16,950
All right.

6
00:00:16,950 --> 00:00:17,370
We're back.

7
00:00:17,400 --> 00:00:18,630
I hope you've given it a try.

8
00:00:18,900 --> 00:00:20,760
Let's do it together over here.

9
00:00:20,760 --> 00:00:25,510
It's mentioned that M is the midpoint of beedi, therefore B.M. is equal to me.

10
00:00:25,830 --> 00:00:28,590
Similarly, M is the midpoint of Acee.

11
00:00:28,620 --> 00:00:31,110
Therefore M is equal to M.C..

12
00:00:31,520 --> 00:00:31,930
All right.

13
00:00:32,110 --> 00:00:38,810
Now let me draw a triangle M, B and DMC in a manner such that they are congruent.

14
00:00:38,820 --> 00:00:39,220
Right.

15
00:00:39,240 --> 00:00:44,530
I just want to draw it in a way that we can visually understand that these two triangles are congruent.

16
00:00:44,820 --> 00:00:49,840
Let me draw a triangle maybe over here and triangle EMCDDA over here.

17
00:00:50,130 --> 00:00:52,530
Now why did I draw it in this position?

18
00:00:52,890 --> 00:00:56,640
We know it equal to M.C. M.B is equal to me.

19
00:00:56,760 --> 00:00:58,350
That's why I've drawn it like this.

20
00:00:58,350 --> 00:01:01,320
Right, so that visually we understand that they are congruent.

21
00:01:01,480 --> 00:01:01,920
All right.

22
00:01:02,130 --> 00:01:07,020
Now over here angle m.b is equal to the angle DMC.

23
00:01:07,170 --> 00:01:08,040
Why is that so.

24
00:01:08,310 --> 00:01:10,800
Because these are vertically opposite angles.

25
00:01:11,010 --> 00:01:13,410
These two angles are vertically opposite angles.

26
00:01:13,410 --> 00:01:13,710
Right.

27
00:01:14,020 --> 00:01:15,930
We know AM is equal to M.C..

28
00:01:16,170 --> 00:01:16,500
Right.

29
00:01:16,500 --> 00:01:17,760
Let me get over here.

30
00:01:18,030 --> 00:01:26,790
You know m.b is equal to me and we have just seen that angle m B is equal to angle c m b therefore Asper

31
00:01:26,790 --> 00:01:30,120
s e s s is congruency rule.

32
00:01:30,300 --> 00:01:33,960
We know that these two triangles are congruent.

33
00:01:33,960 --> 00:01:34,320
Right.

34
00:01:35,380 --> 00:01:44,380
So M.B is Condren, the Triangle CMT now, when two triangles are congruent, their corresponding angles

35
00:01:44,590 --> 00:01:45,960
will be equal, right.

36
00:01:46,120 --> 00:01:48,970
Therefore angle one is equal to angle for an angle.

37
00:01:48,970 --> 00:01:53,770
Three will be equal to angle two now, which would be the correct answer option.

38
00:01:53,980 --> 00:01:58,780
Over here we have angle one is equal to angle four and we see that these two are equal.

39
00:01:58,930 --> 00:01:59,250
Right.

40
00:01:59,270 --> 00:02:01,690
Therefore, the correct answer is option B.
