That irregular polygon is a triangle, and the centroid of a triangle is the point where the medians intersect.
Known the vertices of an IRREGULAR polygon (x1,y1), (x2,y2), (x3,y3)...... and so on how to find its centroid?
I tried to divide the polygon into differrent triangles with a common vertex [say (x1,y1)] and finding their centroids,but i cudn't go further... ... what's the next step?........Please help me out.
I do not know the theorem from geometry which tells how to find centroid of a polygon with a compass and straightedge, if you can tell me I might be able to solve this problem.Originally Posted by ragsk
One thing I know that this gets extremely messy, I one did it for a triangle because I was proving a theorem and the algebraic mess was collasal. But that is only for a triangle I do not know if it will get even more extreme over here I hope not.
