I asked a few friends if they knew how to find the centre of an equilateral triangle, some thought they did but the did not.
So hope this article helps you if you need to do the same .
Find the middle of all three sides.
Then draw a line from the middle to the opposite corner.
Then draw a line from the other middle that you marked and draw a line to the other corner.
Do the same with the last corner to middle.
Where all the lines meet is the centre (centroid) of the Triangle.
