1
00:00:00,730 --> 00:00:01,880
Let's do this question.

2
00:00:02,510 --> 00:00:09,790
Q Is a point in line PR given angle is Cutie's equal to 90 degrees right now.

3
00:00:09,840 --> 00:00:13,240
There are two true or false statements of the video.

4
00:00:13,250 --> 00:00:15,440
Give it a try and then let's do it together.

5
00:00:16,270 --> 00:00:16,710
All right.

6
00:00:17,080 --> 00:00:17,570
We're back.

7
00:00:17,590 --> 00:00:18,830
I hope you've given it a try.

8
00:00:19,030 --> 00:00:23,050
Let me mark these angles, this angle, one angle to an angle three.

9
00:00:23,440 --> 00:00:25,540
Now, the first statement says Angle P.

10
00:00:25,540 --> 00:00:29,860
Q s and angle are Kutty are complimentary.

11
00:00:30,550 --> 00:00:31,390
What does Angle P.

12
00:00:31,390 --> 00:00:33,580
Q s that's angle one over here.

13
00:00:33,820 --> 00:00:36,760
And Arcudi, that's angle three over here.

14
00:00:37,100 --> 00:00:40,190
Now what do we mean with complementary angles.

15
00:00:40,510 --> 00:00:44,660
It means that when you add the two angles you should get ninety degree.

16
00:00:45,010 --> 00:00:45,420
All right.

17
00:00:45,670 --> 00:00:48,910
Now over here, one plus two plus three.

18
00:00:48,940 --> 00:00:52,830
That is, if you add these three angles, you will get 180 degrees.

19
00:00:52,870 --> 00:00:59,930
Right, because this bar is a straight line and we know that a straight angle is equal to 180 degrees.

20
00:01:00,250 --> 00:01:00,710
All right.

21
00:01:00,880 --> 00:01:04,180
Now, it's given that angle two is equal to 90 degrees.

22
00:01:04,480 --> 00:01:04,770
Right.

23
00:01:05,020 --> 00:01:10,690
Therefore, angle one plus angle three is equal to 180 minus 90, which is equal to 90 degrees.

24
00:01:10,900 --> 00:01:15,550
Therefore, when you are adding them, you're getting ninety degrees and hence they are complementary.

25
00:01:15,700 --> 00:01:17,410
And this statement is true.

26
00:01:18,720 --> 00:01:27,090
What about the next statement, and I'll pick you as an angle, you are supplementary angle US is angle

27
00:01:27,090 --> 00:01:32,040
one and angle s Q are is equal, angle two plus angle three.

28
00:01:32,070 --> 00:01:34,500
Right now, supplementary means.

29
00:01:34,500 --> 00:01:38,130
When you add them, you should be getting 180 degrees right now.

30
00:01:38,280 --> 00:01:44,010
Angle one plus angle two plus angle three is equal to 180 degree because we are in a straight line.

31
00:01:44,010 --> 00:01:46,380
So this is a straight angle therefore.

32
00:01:46,710 --> 00:01:48,510
Yes, this is also true.

33
00:01:48,510 --> 00:01:51,750
Right, because you're adding them and you're getting 180 degrees.
