00:00:00,990 --> 00:00:08,460
Students in this video, let's discuss how to find the centroid of a triangle if you are given the three

2
00:00:08,460 --> 00:00:09,780
vertices of the triangle.

3
00:00:10,080 --> 00:00:10,510
All right.

4
00:00:10,680 --> 00:00:14,790
Now, remember, centroid is the meeting point of the mutant's right.

5
00:00:14,940 --> 00:00:16,090
And what is the median?

6
00:00:16,230 --> 00:00:22,290
We have learned that a median is a line that connects a vertex to the midpoint of the opposite side.

7
00:00:22,290 --> 00:00:22,650
Right.

8
00:00:22,800 --> 00:00:28,110
And a triangle will have three median and the median will intersect at the centroid.

9
00:00:28,350 --> 00:00:32,020
Now, do you remember one more interesting property about centroid that we learned?

10
00:00:32,340 --> 00:00:32,780
Yes.

11
00:00:32,940 --> 00:00:38,700
Over here, if I have a triangle and say this is a median and said this is also a median, right at

12
00:00:38,700 --> 00:00:41,150
this point, over here will be my centroid.

13
00:00:41,400 --> 00:00:49,320
And if this is E and this is G and this is B, then we have learned that D divided by GB will be equal

14
00:00:49,320 --> 00:00:50,420
to two by one.

15
00:00:50,430 --> 00:00:50,720
Right.

16
00:00:50,880 --> 00:00:53,670
So I'm just quickly revising what we learned about centroid.

17
00:00:53,970 --> 00:00:55,890
Now let's come to this new topic.

18
00:00:56,100 --> 00:01:01,740
We are trying to learn how to find the centroid of this triangle where we know the tree.

19
00:01:01,740 --> 00:01:02,130
What is.

20
00:01:02,340 --> 00:01:03,960
We know that this is one by one.

21
00:01:04,110 --> 00:01:07,420
This is x2 y two and this is three right now.

22
00:01:07,540 --> 00:01:10,730
It's very easy to find the centroid if you know the what this is.

23
00:01:11,010 --> 00:01:18,600
The centroid is given by the formula x1 plus x2 plus X three by three and Y one plus two plus Y three

24
00:01:18,600 --> 00:01:19,200
by three.

25
00:01:19,350 --> 00:01:25,230
So we just need to add the X coordinates and divide by three and add the Y coordinates and divide by

26
00:01:25,230 --> 00:01:25,590
three.
