Feb 05, 2018 · This point is the triangle's centroid, which will always divide a median into a 2:1 ratio; that is, the centroid is ⅓ the median’s distance from the midpoint, and ⅔ the median’s distance from the vertex. For example, on a median that is 3.6 cm long, the centroid will be 1.2 cm up from the midpoint. Using Averaged Coordinates Help you with what? You say "semicircle". Do you mean the points (x, y) satisfying the equation \(\displaystyle x^2+ y^2= R^2\) with \(\displaystyle y\ge 0\) (and not the half-disk)? You say "center of mass" but don't give a mass or density function. Are we to assume constant density (so strictly speaking you want the "centroid")?
