In triangle PQR, medians PM and QN intersect at G. If the length of median PM is 15 cm, what is the length of the segment PG?

Question

Accepted Answer

1. In any triangle, the medians meet at the centroid G.
2. The centroid divides each median in the ratio **2:1** from the vertex to the midpoint.
3. Thus $PG=	frac{2}{3}	imes PM = 	frac{2}{3}	imes 15 = 10$ cm.
