In △ABC, the medians BE and CF intersect at G. AGD is a line meeting BC at D. If GD is 1.5 cm, then AD is equal to -
2.5 cm
3 cm
4 cm
4.5 cm
SInce, AD is the median and G is centroid, (AG : GD = 2 : 1\)
⇒GD:AD=1:3
⇒AD:GD=3:1
⇒ADGD=31
⇒AD1.5=3
⇒AD=4.5 cm
In triangle ABC, the medians BE and CF intersect at G. AD is a line meeting BC at D. If GD is 1.5 cm, then the value of AD is .
In △ABC, the medians BE and CF intersect at G. AD is a line meeting BC at D. If GD is 1.5 cm, then find the value of AD.
