Let A(4,2), B(6,5) and C(1,4) be verticesoftriangle ABC. (i) median from A meets BC at D. Find the co ordinates of the point D. (ii) find the co ordinatesof the point P on AD such that AP :DP= 2:1 (iii) find the length of AD.

median means mid point of two point in co-ordinate geometry.
so, find mid point of BC I.e. {(6+1)/2, (5+4)/2}=(7/2,9/2)
2) use section formula
P(11/3,11/3)
