00:00:00,590 --> 00:00:07,580
Let's do this question, which of the following cannot be the sides of a triangle was the video give

2
00:00:07,580 --> 00:00:09,600
it a try and then let's do it together.

3
00:00:10,130 --> 00:00:10,640
All right.

4
00:00:10,640 --> 00:00:11,620
Let's do it together.

5
00:00:11,900 --> 00:00:16,760
The sum of the two sides of a triangle has to be greater than the third side.

6
00:00:16,910 --> 00:00:17,260
Right.

7
00:00:17,630 --> 00:00:19,340
So let's check the options.

8
00:00:20,090 --> 00:00:26,270
What about option A three, four and five, four, three plus four gives me seven.

9
00:00:26,300 --> 00:00:27,440
That's greater than five.

10
00:00:27,860 --> 00:00:29,840
Four plus five gives me nine.

11
00:00:29,840 --> 00:00:33,020
That's greater than three and three plus five gives me eight.

12
00:00:33,140 --> 00:00:34,250
That's greater than four.

13
00:00:34,280 --> 00:00:35,020
So that's fine.

14
00:00:35,180 --> 00:00:36,320
What about option B?

15
00:00:36,470 --> 00:00:39,080
You have two, four and six right now.

16
00:00:39,080 --> 00:00:41,720
Two plus four is equal to six.

17
00:00:41,840 --> 00:00:45,440
But we know that it should have been greater if that's a valid triangle.

18
00:00:45,650 --> 00:00:49,130
Therefore, two, four and six cannot form a triangle.

19
00:00:49,310 --> 00:00:52,100
And hence the answer is option B.
