Knowing CENTROID/GEO-CENTRE
Hello math bugs(π) and hivers(π)
I hope you are strong and stout.
I feel something ;let me clear it.
βοΈβοΈSome people may think everyday I have posting same triangle.I should reply them with Hahaπ . No man every concept I share here is different from one another and the beauty is No figure use here is a copy of previous one. If you measure them, I am sure, you will definately find them of different sizes.Though I have never measured them with a scaleπ. I took the sizes that suit the space to put my sufficient words.β
Let's get back to the topic:
A centroid is a point inside a triangle(any of its kind) from by three medians after intersecting each other. Unlike cir-cum-centre it can't be outside or on the side of a triangle.
MEDIAN: A median is a line segment which connects a vertex and the mid point of opposite side of a triangle.
Check median below:
VERTEX: A vertex is a point where two sides of a triangle meet.
Check vertex below:
In the figure below, the point "O" at the centre in green colour is the centroid. E is the mid point of AB, F is the mid point of BC and D is the mid point of AC.
Let me make it simple. Suppose you have a triangle shaped plain rock and you wanna balance it on a nail for that the triangle shaped rock do not fell off and the point you find to do that is the Centroid. That's why Centroid is also called geo-centre.
Centroid: O in green colour
Points to be considered:
- β The centroid doesn't make any circle touching the three vertices.
- β Medians divide a triangle into six equal areas irrespective of its kind.
- β The smaller triangle thus made may not be similiar triangle unlike equilateral one.
- β A median also divide a triangle into two equal areas.
- β A centroid always be inside the triangle.
Test:
Your Options are:
- 40 square cm.
- 44 square cm.
- 48 square cm.
- 52 square cm.
Topic on the way: Ortho-centre
I hope you have liked my efforts.

Really cool work bro you are doing it all the time. When I was in the primary school these centroids and other related things confused me as these became mixed with each other.
Hello @uop
Thank you for visiting and supporting.
I used to have the same problem.
That's why I am trying to make it easy if I can help anyone.
HAHA Perfect :) Mathematics in the Hive π
I think the answer is 48, right?
Yeah you got it.
Thanks for replying man.
I am working on visuals.It attacks the audience.
That's why I got 650+ β€οΈ in one of my post.ππ
That's cool. Visuals, yess, I see. Good luck :)
Yay! π€

Hello @meta007 very good information on geometry. Very nice presentation of your post and nice pictures that make it easy to understand. Making the training dynamic and friendly.
Many successes
Health and wellness to you.
Aha thank you for replying.
I am glad you have liked it.
Simple and precise. How I wish I read this when in high school ,maybe I would have been a mathematician just like youπ. More power to your elbow
Hero!
