00:00:00,720 --> 00:00:06,420
Let's do this question, one of the diagnose of a rhombus and its sites are equal.

2
00:00:06,720 --> 00:00:08,640
Find the angles of the rhombus.

3
00:00:08,940 --> 00:00:12,720
All right, pause the video, give it a try, and then let's do it together.

4
00:00:13,290 --> 00:00:13,680
All right.

5
00:00:13,680 --> 00:00:14,140
We're back.

6
00:00:14,160 --> 00:00:15,480
I hope you have given it a try.

7
00:00:15,720 --> 00:00:16,820
Let's do it together.

8
00:00:17,100 --> 00:00:17,640
Over here.

9
00:00:17,640 --> 00:00:19,730
You have Rhombus ABCDE.

10
00:00:20,070 --> 00:00:21,690
Let's construct its diagonals.

11
00:00:21,700 --> 00:00:27,950
That's beauty and AC let the length of the side of the rhombus be of eight centimeters.

12
00:00:28,260 --> 00:00:28,800
All right.

13
00:00:28,980 --> 00:00:35,640
Now, let's say beauty is equal to it because it's given that one of the diagonals of the rhombus is

14
00:00:35,640 --> 00:00:36,720
equal to the side.

15
00:00:36,870 --> 00:00:37,280
All right.

16
00:00:37,740 --> 00:00:45,380
Now let's mark these angles over here as angle one angle to angle three and angle for now.

17
00:00:45,480 --> 00:00:47,520
Consider a triangle a beauty.

18
00:00:47,730 --> 00:00:54,780
Right now you can see that abs of lengthy it is of length and beauty is also of length.

19
00:00:55,350 --> 00:00:59,580
So Triangle Abady is an equilateral triangle, right?

20
00:00:59,760 --> 00:01:06,270
Therefore, angle is equal to sixty degrees and angle one and angle two also is equal to sixty degrees.

21
00:01:06,510 --> 00:01:06,880
Right.

22
00:01:07,050 --> 00:01:15,090
Similarly you will see that triangle CBD is also an equilateral triangle and hence angle three equals

23
00:01:15,150 --> 00:01:20,690
angle four is equal to sixty degrees and angle is also includes sixty degrees.

24
00:01:20,940 --> 00:01:23,850
Now therefore the angles of the rhombus.

25
00:01:23,850 --> 00:01:30,470
That's what we have to find out is 60, 60 and 120 and 120 degree right.

26
00:01:30,600 --> 00:01:38,910
Angle A 60 angle C 60 and angle BS angle one plus angle three, angle one is sixty and angle three sixty

27
00:01:39,150 --> 00:01:39,450
two.

28
00:01:39,450 --> 00:01:41,430
Angle B is 120 degrees.

29
00:01:41,670 --> 00:01:45,870
Similarly Angle D is also equal to 120 degrees.
