Students in this video, let's discuss how to find the centroid of a triangle if you are given the three
vertices of the triangle.
All right.
Now, remember, centroid is the meeting point of the mutant's right.
And what is the median?
We have learned that a median is a line that connects a vertex to the midpoint of the opposite side.
Right.
And a triangle will have three median and the median will intersect at the centroid.
Now, do you remember one more interesting property about centroid that we learned?
Yes.
Over here, if I have a triangle and say this is a median and said this is also a median, right at
this point, over here will be my centroid.
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
to two by one.
Right.
So I'm just quickly revising what we learned about centroid.
Now let's come to this new topic.
We are trying to learn how to find the centroid of this triangle where we know the tree.
What is.
We know that this is one by one.
This is x2 y two and this is three right now.
It's very easy to find the centroid if you know the what this is.
The centroid is given by the formula x1 plus x2 plus X three by three and Y one plus two plus Y three
by three.
So we just need to add the X coordinates and divide by three and add the Y coordinates and divide by
three.
