Question
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?Solution
Given: AD is the median of triangle ABC. P is the centroid of triangle ABC. If AP = 14 cm Concept used: The centroid of the triangle divides each of its median in the ratio 2:1. Calculation: AP/PD = 2/1 14/ PD = 2/1 PD = 14/2 PD = 7cm
