AD is the median of triangle ABC. P is the centroid of triangle ABC. If AP = 14 cm, then what is the length of PD ?
Answer & explanation
Correct answer: option 4
We know that,
The centroid of the triangle divides each of its median in the ratio 2:1.
AP = 14 cm
\(\frac{AP}{PD}\) = \(\frac{1}{2}\)
\(\frac{14}{PD}\) = \(\frac{1}{2}\)
PD = \(\frac{14}{2}\) = 7cm
