Question

Ps is the median of triangle pqr and o is the centroid such that po=20cm. The length of os is

Answer 1

Given : p s  is the median of triangle p q r and o is the centroid such that p o= 20 cm

To Find: Length of o s

Solution : As ps is the median of a triangle, and o is the centroid

so,→ po : os = 2:1  [centroid of a triangle divides the median in the ratio as 2:1.]

→$\frac{20}{os}=\frac{2}{1}$

→ 2× os = 20

→ os =20÷2

→ os = 10 cm
