First we enter the number of side polygons then system show the required boxes to enter the x, y coordinates. The centroid of a triangle. For instance, the centroid of a circle and a rectangle is at the middle. Also, a centroid divides each median in a 2:1 ratio (bigger part is closer to the vertex). A non-convex object might have a centroid that is outside the figure itself. However, if you're searching for the centroid of a polygon - like a rectangle, a trapezoid, a rhombus, a parallelogram, an irregular quadrilateral, or another polygon- it is unfortunately a bit more complicated. Centroid calculator is an online tool that can be used to calculate the centroid of a triangle. In a triangle, the centroid is the point at which all three medians intersect. To find the centroid of a triangle ABC you need to find average of vertex coordinates. In our case, we will choose N-sided polygon. Calculate Centroid Of a Semi Circle With Radius r = 5cm.
