Question

find centre of mass of a right angled triangle

Answer 1

For a right triangle, the centroid can be located as follows. From the right angle, measure one-third of the distance along the two adjacent sides to the other vertices. Draw lines at right angles to the sides at the one-third points, and the intersection of the lines should be the centroid.

More generally for any triangle, with vertices L, M and N, which have co-ordinates (xL, yL), (xM, yM) and (xN, yN), respectively, the centroid should be located at the point:

(1/3(xL + xM + xN), 1/3(yL + yM + yN))

Getting the centroid of triangles using the more general formula for a closed polygon doesn’t seem to work, but the above methods should.
